It aims to collect and preserve the evidence so that it can be used in court at some time. We have to record the scene to provide a permanent record of what we see and use in court to give the jury an idea of what the crime scene looked like when the event occurred and to begin an investigation. Photographs are also taken for complete and complete documentation of the crime scene
- The first step is scale measurement: Victims are placed inside the crime scene to document the evidence that will be inside the scene of the crime. The marker is used to help organize the evidence, so that when the document on a piece of paper can correspond a number with the element there is. A scale is placed on the edge of each marker in parallel with the evidence element that helps you each time you take pictures and can get accurate information.
- The second step is to create a diagram: Whatever the evidence measures is that a scale diagram is made of each crime scene, using tape measures and we would execute an X axis and a Y axis its X axis will be its baseline and its Y axis is According to how it measures its points outside of its X axis, it will be possible to distinguish the distance between elements of evidence and pieces of furniture in the windows of the doors of the rooms. When the sketch is made, we will know exactly how and where they are in relation to other things in the room.
- Third step is to look for fingerprints and DNA: Search common areas such as doorknobs or padlocks anywhere any person has touched something to enter or leave a room in which DNA is examined. These are areas where fingerprints are usually sought. DNA is also your biological imprint, Each person is different, except if you have an identical twin, then that twin will have the same DNA as you. You can find DNA and saliva. You can find it in the blood, you can find it in the skin cells from where anyone touched a surface, clean the area in question and then put it back in a portion of an envelope, then secure it and seal it inside another envelope. Once the crime labs obtain them, they will remove them from the package in a sterile environment and examine them for DNA and there is a possibility that there are people who come with DNA on a swab of a goatee, but the crime lab has the technology to be able to separate those DNA into separate individuals.
- The fourth step is making the cases: When the collected evidence is combined with other investigative work, such as suspect interrogations and forensic sketches, a case can be brought to trial. Integrity is what shines when it appears before the court. The defense will often try to attack the integrity of the officer who is conducting the investigation to create reasonable doubts and put your client in account when you have integrity and everything he does, making it very difficult for them to present the case.
When arriving at the scene of the crime, and before entering it properly, first of all, whoever leads the team of Criminalistics Experts, should get information about what happened from the people who discovered the event, to avoid misrepresentations when performing the crime. Field work. After processing said information, the scene of the crime must be intervened. In the first place, basic bio-security, that is, they will use the necessary suits for the protection of their physical integrity (gloves, helmets, masks, etc.) It is the intervening experts who decide the degree of importance of each evidence or evidence found; starting from the generic to the specific, and from the outside to the inside of the Crime Scene; in such a way that they are correctly numbered, perennized and collected from their place in the case of footprints found on concrete ground, the sample can be taken with an adhesive tape or with photographic shots with low light. To measure to scale it is important to mark or to put a signal, that only the expert team distinguishes, to each sign and / or evidence. Once he has collected all the possible information about the criminal facts, its context, the victims and their environment, the detective elaborates logical hypotheses based on these data. It must work in a spiral, starting from the suspicious person: his personality, his background, his economic level, his personal relationships, the activities he performs ... Here, the arrest, interrogation and search of the suspects' home is contemplated. You can also resort to other sources and compare crime with similar crimes. All this in order to identify the perpetrators of the crime and establish their responsibility in it.
Steps to investigate a scene of a crime: 1.Measurement of the scale: The victims are placed inside the crime scene to document the evidence that will be inside the scene of the crime. The marker is used to help organize the evidence, so that when the document on a sheet of paper can correspond a number with the item there is. A scale is placed on the edge of each marker in parallel with the evidence element that helps you each time you take pictures and can obtain accurate information. 2.Create a diagram: Whatever the measure of the evidence, it is that a scale diagram of each crime scene is made, using metric tapes and we would execute an X axis and a Y axis, its X axis will be its baseline and its Y axis is of According to the way you measure your points outside of your X axis, it will be possible to distinguish the distance between evidence elements and furniture in the windows of the room doors. When the sketch is made, we will know exactly how and where they are in relation to other things in the room.
3.Find fingerprints and DNA: Look in common areas like doorknobs or padlocks where anyone has touched something to enter or leave a room in which DNA is examined. These are areas where fingerprints are usually sought. DNA is also your biological fingerprint. Each person is different, except if you have an identical twin, then that twin will have the same DNA as you. You can find DNA and saliva. You can find it in the blood, you can find it in the skin cells from where someone touched a surface, clean the area in question and then put it back in one part of an envelope, then secure it and seal it inside another envelope. Once the crime labs obtain them, they will remove them from the package in a sterile environment and examine them for DNA, and there is a possibility that there may be people who come with DNA on a swab of a goose, but the crime lab has the technology to be able to separate those DNA into separate individuals.
4.Make the cases: When the evidence collected is combined with other investigative work, such as suspect interrogations and forensic sketches, a case may be brought to trial. Integrity is what shines when it appears in court. The defense will often try to attack the integrity of the officer who is conducting the investigation to create reasonable doubts and put your client in mind when you have integrity and everything you do, which makes it very difficult for them to present the case .
The first thing we do in a crime scene is, first the police are in charge of watching the scene until the investigators arrive and they are covered with their appropriate clothes. The identification of the victim is sought if there is, the evidence begins to be collected or extracts are placed yellow objects with numbers to identify presumed evidence that may help the case, the photographer is responsible for collecting the least by the camera, ultraviolet light is to identify if there are signs of blood or other substances, the place is measured in where is the victim to possibly identify how he could get to be like this and other things. Apart from that, there is a team dedicated to a job that is to search for DNA, or evidence that can be found with a suspect, such as fingerprints, hair, among others.
When the investigator arrives on the scene, the first thing to do is observe the crime scene to obtain a signal or mark to help him solve the crime. The objective of these investigators is to collect and safeguard the evidence and then use it in court. The scene is completely taxed to be used in court and the judge to see exactly how the crime scene looked. photos and videos of the scene are taken in case after another time another researcher wishes to reopen the case he can use the photos and videos taken at the moment of the scene and can feel at that moment; Therefore, these evidences must be clear and real. although at some point some photos seem insignificant. for another researcher it may be good evidence. An alternative light is used to see evidence that is not visible to the naked eye or has tried to eliminate as blood or a chemical. the evidences are marked with numbers to organize them and make a diagram that helps us to solve the case. This diagram also helps us with the distance that exists between one evidence and another or between the body of the victim and the evidence. fingerprints are searched for in common places such as door handles or any object that the criminal may have used to enter or leave the scene of the crime or room. DNA is also looked for in places where fingerprints may be, saliva, blood or a piece of skin can be found. These DNAs are taken to the laboratories to be analyzed. at the end all the evidence is collected and taken to court for trial and to end the case. the evidence must be collected correctly, because if the defendant's lawyer is not done, he will always try to attack the veracity of the evidence to dismiss the case and say that the evidence is contaminated.
OBSERVATION AND ANALYSIS OF THE FACTS The objective of this first stage is to find out how the events occurred and what means were used to commit the crime. You can see all the elements that can be identified and identify the author, at least, demonstrate their presence in the place. When a detective arrives at the scene of a crime, it must be a protected perimeter to preserve any clue until the arrival of the scientific police, which will be responsible for documenting, measuring and photographing each element. Then, the investigator will identify the direct witnesses, after a brief verbal interrogation, will lead to an isolated place to take a written statement. This phase also includes the registration of the victim's address or the sites where you can find agendas, notes and the entire document so you can discover how to do it, with whom you relate and what you do.they also do a study with the DNA of the person looking for some evidence that helps them clarify the case, for that they have technological laboratories that help them find the culprit of the crime
Our goal is to collect and preserve evidence that can be used in court to immerse yourself in an idea.of how the crime scene looked like we approached and began our investigation, we took photographs to fully and completely document the crime scene It is auxiliary with the results of the scientific applications of their knowledge, methodology and technology to the organs that seek and administer justicein order to provide them with evidentiary elements and reconstructors conducive to conoser the technical and historical. 1- the photograph is made how the crime scene would look as we approached and began our investigation, we took photographs to fully and completely document the crime scene, to have details of the view of the objects that were on the scene. 2-Second step is what is called alternative light source now this source emits different light waves and light is measured in waves and the different waves create different colors, then the color and the protective glasses and when I combined these two colors together, it filters certain links of wavelengths of light and allows me to see physical evidence that may be in the body or at the crime scene that can not be seen with the naked eye, we call this evidence of gross, so the purpose of collecting evidence physical and, to trace evidence is to determine who could have been at this crime scene, which helps us determine who committed the crime. 3-third step measuring to scale we have the markers that are named 1 through the many we need, we put them inside the crime scene to document the evidence that will be inside the placement of markers helps you organize your evidence so that when the document on a paper may correspond a number with the element there. 4-anyone touched a surface, we cleaned the area in question and then we put it back in one part of the envelope, we secured it and sealed it inside another envelope once. The crime lab obtains them, removes them from the package in a sterile environment and analyzes them to determine their DNA.
When arriving at the scene of the crime the specialists who follow some steps to initiate the investigation Before entering the crime scene, specialists have the ability to preserve the evidence found on the scene. Measure an escalation: used to document the evidence at the crime scene. Markers help organize the evidence when writing a report. Create a diagram: in each crime scene the diagram is important because it will be the line of its axis and it will be how you measure your points. Find fingerprints and DNA: sow in the scene can be searched in common areas such as locks, door knobs and in places where a person may have been touched to leave or move as an object, along with fingerprint collection can also be collected DNA and Sea of blood, saliva or skin once found the evidence will be processed in the laboratory. Taking into account some steps for data collection at a crime scene if it is carried out during the process.
It is admirable how science mathematics and photography can help solve a murder mystery. When we are called to the crime scene, our goal is to collect and preserve the evidence that can be used in court. When we approached and began our investigation, we took photographs to document the crime scene completely. if something happens and the culprit is not found. if in 40 years another researcher decides to reopen the case they can look at my photographs and feel that they are in the room, so that's why I take many photographs.
after taking pictures and recording the video. I use what is called videotaping and the photo I use that is called a light source. This light emits different waves of light. Today, it emits blue light and yellow lenses and when I combine these two colors together, it filters certain links of wavelengths of light and allows me to see physical evidence that may be in the body or at the crime scene that can not be seen with the naked eye and know who was at the crime scene and find the criminal.
Saliva can be in the blood that can be found in skin cells. The crime lab obtains them, removes them from the package in a sterile environment and analyzes them to determine their DNA. in separated individuals. combining with suspect interrogations and forensic skeches a case can be brought to integrity. that is when you go to court the defense will often try to attack the integrity of the officer. When you have integrity, the case becomes very difficult.
OBSERVATION AND ANALYSIS OF THE FACTS The objective of this first stage is to find out how the events occurred and what means were used to commit the crime. It also includes all the elements that allow searching and identifying the author or, at least, demonstrate their presence in the place. When a detective arrives at the scene of a crime, he must establish a protected perimeter to preserve any clue until the arrival of the scientific police, which will be in charge of documenting, measuring and photographing each element. The investigator will then identify the direct witnesses and, after a brief verbal interrogation, will take them to an isolated place to take a written statement. This phase also includes the registration of the victim's home or of those sites where agendas, notes and any document can be found to discover what it is like, with whom it is related and what it is dedicated to. ELABORATION OF HYPOTHESIS Once he has collected all the possible information about the criminal facts, its context, the victims and their environment, the detective elaborates logical hypotheses based on these data. This task must also be systematic, starting with the most plausible theory and exploiting each one in depth. It must work in a spiral, starting from the suspicious person: his personality, his background, his economic level, his personal relationships, the activities he performs ... Here, the arrest, interrogation and search of the suspects' home is contemplated. You can also resort to other sources and compare crime with similar crimes. All this in order to identify the perpetrators of the crime and establish their responsibility in it.
In this summary I was able to read each of the parts to follow in a crime study ... Get closer to the scene The crime scene investigator returns the microphone to his clip and begins to lead to the last assignment. A crime scene investigation begins long before the CSI enters a structure, an open field or a wooded area. In general, the message of radio dispatch is brief and rarely reveals the full nature of the incident. In most cases, this is done to avoid drawing viewers and the media that may be monitoring the frequency of sending. Secure and protect the scene Hopefully, the first responders have not caused too many interruptions in any potential physical evidence. Before even entering the structure, entry and exit must be controlled. Entries must be placed in all possible entries. Start a preliminary survey Again ... before entering the structure an external inspection is needed. This may be nothing more than walking around the outside of the structure to see if any obvious evidence is evident. This would include open windows, damaged doors, stairs and the like. The question the CSI asks is ... how was the entrance to the structure made? Once inside, the CSI will perform a visual inspection of the actual room in which the reported incident occurred. This is a good time to take general photos of the scene. Then, it will examine the adjoining rooms to determine if these spaces may have information related to the incident. The very nature of what seems obvious should trigger the thinking processes of the ITUC. What happened here, when did it happen and what kind of evidence should be present? The questions that must be answered initially are: Did the shooting happen in this room? and among others. Make sure you have general, mid-range, and close-up shots of any potential physical evidence. Be sure to include scales in the close-ups. Many CSIs will prepare the rough sketch at the scene and complete a detailed sketch at headquarters. The rough sketch must contain neither more nor less than the detailed final sketch. It is always recommended that an assistant help you take measurements, and it is a good idea for this person to check each measurement to avoid further questions. As the potential evidence is located, it should be recorded in the crime scene sketch, as well as in the the pictures. If your agency offers the luxury of having a cameraman, the video often tells a compelling story for a jury.
Evidence from the crime scene is useless unless it is properly marked and packaged and a Chain of Evidence is initiated from the moment it is removed. Use the appropriate type of containers for all collected tests. Never pack objects wet with blood or other physiological fluids in plastic bags, as this will accelerate decomposition. Label and identify all collected evidence, including notes taken by the investigator. Make sure that each packet that contains physical evidence is collected, leave nothing behind. Take a final tour to make sure all potential evidence is packaged and labeled. and finally Free the crime scene While it is normal for other people interested in the property to want to regain access, the CSI should not be rushed, persuaded or intimidated to release the scene until the work is completed.
First step: With a video camera the scene is recorded and used in court so that the jury has an idea of what was the scene of the crime.
Second step: Photographs are taken of everything, and documented, even if it is irrelevant, since if the case is not resolved, several years later it could be and the photographs would help.
Third step: The alternate light source is used that can reveal physical evidence that can not be perceived by the naked eye.
Fourth step: Measure to scale, this step is used to document the evidence in detail and where it is located in the scene, helps organize the evidence and correspond to the label and take pictures of the element with the scale that represents it.
Fifth step: Create a diagram to know and to have a notion of how far the evidence of the corpse was or at what distance there was evidence of another and of the spaces and elements within the room or the area in which the event occurred.
Sixth step: Fingerprints and DNA, this step makes the job of looking for suspects less tedious, since the traces and the DNA that are never identical unless you are twin, give distinction of the people who were in the place or in contact with the victim at that moment.
Seventh step: Making the case; when the evidence collected is combined with other lines of investigation the case is brought to trial and all this is done to do justice and enforce the law.

1- cordon the area to avoid contamination of the same by external. 2 - use of equipment to avoid contamination of the area such as hoberol, covers mouths, lenses and others. 3- Collect photographs of the scene at first instance. 4- Identification numbers are placed in each clue found in the scene. 5- Proceed to take pictures of the signs with their respective numbers. 6- perform a scale measurement for the creation of a crime diagram. 7- we proceed to the use of ultraviolet light accompanied by yellow lenses to look for any stain either blood or other fluid in the ecsena or the victim. 8 - verification of fingerprints on the surfaces of the scene. 9- proceed to the lifting of the signs and they are saved. 10. perform the reconstruction of the case if necessary and possible.
Bianca Culiolis 8-828-1231 For the collection of signs in a scene we must have an order, technique and methods to avoid contamination of them, we must be very observant and not overlook any detail, take pictures, protect is to take all steps and measures to ensure the purity of the evidence, stored correctly in its packaging in order to send it to the laboratories for proper analysis. As criminalists, professionalism is key to avoiding mistakes.
Our goal is to find and preserve the evidence. so that it can be used in court at some point, we take a video camera and record all the sound and what is treated in a permanent record of what we see when we enter and that is used in court to give the jury an idea How to see the crime scene, a measure that we approached and began our investigation, we took photographs to fully and completely document the crime scene. We have the markers that are numbered from 1 to 1, however, many of us need to place them inside the crime scene to document the evidence that will be inside the scene of the crime. The placement of the markers will help you organize your evidence, so that the paper document can do so. Scale diagram of each crime scene using a tape measure and an axis axis and its axis and its baseline, its axis and its shape. A fingerprint is always something that we look for and we randomly search in common areas like doorknobs or padlocks in any place where any person would have touched something. If we enter or leave a room where we look for DNA in the areas where we usually look for fingerprints This is their biological fingerprint. They will withdraw from the package in a sterile environment and the DNA test and there is a possibility that people get the DNA with a swab from a doorknob but there is our crime the laboratory has the technology to separate those DNA in the separated individuals When the collected evidence is combined with other research works Integrity is what shines when it comes to courts. Often, the defense will attempt to attack the integrity of the officer.

OBSERVATION AND ANALYSIS OF THE FACTS
ResponderBorrarThe objective of this first stage is to find out how the events occurred and what means were used to commit the crime. You can see all the elements that can be identified and identify the author, at least, demonstrate their presence in the place.
When a detective arrives at the scene of a crime, it must be a protected perimeter to preserve any clue until the arrival of the scientific police, which will be responsible for documenting, measuring and photographing each element.

ResponderBorrar1- the photograph is made how the crime scene would look as we approached and began our investigation, we took photographs to fully and completely document the crime scene, to have details of the view of the objects that were on the scene.
2-Second step is what is called alternative light source now this source emits different light waves and light is measured in waves and the different waves create different colors, then the color and the protective glasses and when I combined these two colors together, it filters certain links of wavelengths of light and allows me to see physical evidence that may be in the body or at the crime scene that can not be seen with the naked eye, we call this evidence of gross, so the purpose of collecting evidence physical and, to trace evidence is to determine who could have been at this crime scene, which helps us determine who committed the crime.
3-third step measuring to scale we have the markers that are named 1 through the many we need, we put them inside the crime scene to document the evidence that will be inside the placement of markers helps you organize your evidence so that when the document on a paper may correspond a number with the element there.
4-anyone touched a surface, we cleaned the area in question and then we put it back in one part of the envelope, we secured it and sealed it inside another envelope once. The crime lab obtains them, removes them from the package in a sterile environment and analyzes them to determine their DNA.

ResponderBorrarBefore entering the crime scene, specialists have the ability to preserve the evidence found on the scene.
Measure an escalation: used to document the evidence at the crime scene. Markers help organize the evidence when writing a report.
Create a diagram: in each crime scene the diagram is important because it will be the line of its axis and it will be how you measure your points.
Find fingerprints and DNA: sow in the scene can be searched in common areas such as locks, door knobs and in places where a person may have been touched to leave or move as an object, along with fingerprint collection can also be collected DNA and Sea of blood, saliva or skin once found the evidence will be processed in the laboratory.
Taking into account some steps for data collection at a crime scene if it is carried out during the process.
It is admirable how science mathematics and photography can help solve a murder mystery. When we are called to the crime scene, our goal is to collect and preserve the evidence that can be used in court. When we approached and began our investigation, we took photographs to document the crime scene completely. if something happens and the culprit is not found. if in 40 years another researcher decides to reopen the case they can look at my photographs and feel that they are in the room, so that's why I take many photographs.
ResponderBorrarafter taking pictures and recording the video. I use what is called videotaping and the photo I use that is called a light source. This light emits different waves of light. Today, it emits blue light and yellow lenses and when I combine these two colors together, it filters certain links of wavelengths of light and allows me to see physical evidence that may be in the body or at the crime scene that can not be seen with the naked eye and know who was at the crime scene and find the criminal.
Saliva can be in the blood that can be found in skin cells. The crime lab obtains them, removes them from the package in a sterile environment and analyzes them to determine their DNA. in separated individuals. combining with suspect interrogations and forensic skeches a case can be brought to integrity. that is when you go to court the defense will often try to attack the integrity of the officer. When you have integrity, the case becomes very difficult.
we owe it to the victims.
we owe it to society.
OBSERVATION AND ANALYSIS OF THE FACTS
ResponderBorrarThe objective of this first stage is to find out how the events occurred and what means were used to commit the crime. It also includes all the elements that allow searching and identifying the author or, at least, demonstrate their presence in the place.
When a detective arrives at the scene of a crime, he must establish a protected perimeter to preserve any clue until the arrival of the scientific police, which will be in charge of documenting, measuring and photographing each element. The investigator will then identify the direct witnesses and, after a brief verbal interrogation, will take them to an isolated place to take a written statement.
This phase also includes the registration of the victim's home or of those sites where agendas, notes and any document can be found to discover what it is like, with whom it is related and what it is dedicated to.
ELABORATION OF HYPOTHESIS
Once he has collected all the possible information about the criminal facts, its context, the victims and their environment, the detective elaborates logical hypotheses based on these data. This task must also be systematic, starting with the most plausible theory and exploiting each one in depth.
It must work in a spiral, starting from the suspicious person: his personality, his background, his economic level, his personal relationships, the activities he performs ... Here, the arrest, interrogation and search of the suspects' home is contemplated.
You can also resort to other sources and compare crime with similar crimes. All this in order to identify the perpetrators of the crime and establish their responsibility in it.
In this summary I was able to read each of the parts to follow in a crime study ... Get closer to the scene The crime scene investigator returns the microphone to his clip and begins to lead to the last assignment. A crime scene investigation begins long before the CSI enters a structure, an open field or a wooded area. In general, the message of radio dispatch is brief and rarely reveals the full nature of the incident. In most cases, this is done to avoid drawing viewers and the media that may be monitoring the frequency of sending.
ResponderBorrarSecure and protect the scene
Hopefully, the first responders have not caused too many interruptions in any potential physical evidence. Before even entering the structure, entry and exit must be controlled. Entries must be placed in all possible entries. Start a preliminary survey
Again ... before entering the structure an external inspection is needed. This may be nothing more than walking around the outside of the structure to see if any obvious evidence is evident. This would include open windows, damaged doors, stairs and the like. The question the CSI asks is ... how was the entrance to the structure made? Once inside, the CSI will perform a visual inspection of the actual room in which the reported incident occurred. This is a good time to take general photos of the scene. Then, it will examine the adjoining rooms to determine if these spaces may have information related to the incident. The very nature of what seems obvious should trigger the thinking processes of the ITUC. What happened here, when did it happen and what kind of evidence should be present? The questions that must be answered initially are: Did the shooting happen in this room? and among others. Make sure you have general, mid-range, and close-up shots of any potential physical evidence. Be sure to include scales in the close-ups. Many CSIs will prepare the rough sketch at the scene and complete a detailed sketch at headquarters. The rough sketch must contain neither more nor less than the detailed final sketch. It is always recommended that an assistant help you take measurements, and it is a good idea for this person to check each measurement to avoid further questions. As the potential evidence is located, it should be recorded in the crime scene sketch, as well as in the the pictures. If your agency offers the luxury of having a cameraman, the video often tells a compelling story for a jury.
Evidence from the crime scene is useless unless it is properly marked and packaged and a Chain of Evidence is initiated from the moment it is removed. Use the appropriate type of containers for all collected tests. Never pack objects wet with blood or other physiological fluids in plastic bags, as this will accelerate decomposition. Label and identify all collected evidence, including notes taken by the investigator. Make sure that each packet that contains physical evidence is collected, leave nothing behind. Take a final tour to make sure all potential evidence is packaged and labeled.
and finally
Free the crime scene
While it is normal for other people interested in the property to want to regain access, the CSI should not be rushed, persuaded or intimidated to release the scene until the work is completed.
First step:
ResponderBorrarWith a video camera the scene is recorded and used in court so that the jury has an idea of what was the scene of the crime.
Second step:
Photographs are taken of everything, and documented, even if it is irrelevant, since if the case is not resolved, several years later it could be and the photographs would help.
Third step:
The alternate light source is used that can reveal physical evidence that can not be perceived by the naked eye.
Fourth step:
Measure to scale, this step is used to document the evidence in detail and where it is located in the scene, helps organize the evidence and correspond to the label and take pictures of the element with the scale that represents it.
Fifth step:
Create a diagram to know and to have a notion of how far the evidence of the corpse was or at what distance there was evidence of another and of the spaces and elements within the room or the area in which the event occurred.
Sixth step:
Fingerprints and DNA, this step makes the job of looking for suspects less tedious, since the traces and the DNA that are never identical unless you are twin, give distinction of the people who were in the place or in contact with the victim at that moment.
Seventh step:
Making the case; when the evidence collected is combined with other lines of investigation the case is brought to trial and all this is done to do justice and enforce the law.

steps to investigate a scene
ResponderBorrar1- cordon the area to avoid contamination of the same by external.
2 - use of equipment to avoid contamination of the area such as hoberol, covers mouths, lenses and others.
3- Collect photographs of the scene at first instance.
4- Identification numbers are placed in each clue found in the scene.
5- Proceed to take pictures of the signs with their respective numbers.
6- perform a scale measurement for the creation of a crime diagram.
7- we proceed to the use of ultraviolet light accompanied by yellow lenses to look for any stain either blood or other fluid in the ecsena or the victim.
8 - verification of fingerprints on the surfaces of the scene.
9- proceed to the lifting of the signs and they are saved.
10. perform the reconstruction of the case if necessary and possible.
ResponderBorrarBianca Culiolis 8-828-1231
For the collection of signs in a scene we must have an order, technique and methods to avoid contamination of them, we must be very observant and not overlook any detail, take pictures, protect is to take all steps and measures to ensure the purity of the evidence, stored correctly in its packaging in order to send it to the laboratories for proper analysis. As criminalists, professionalism is key to avoiding mistakes.
Our goal is to find and preserve the evidence. so that it can be used in court at some point, we take a video camera and record all the sound and what is treated in a permanent record of what we see when we enter and that is used in court to give the jury an idea How to see the crime scene, a measure that we approached and began our investigation, we took photographs to fully and completely document the crime scene. We have the markers that are numbered from 1 to 1, however, many of us need to place them inside the crime scene to document the evidence that will be inside the scene of the crime. The placement of the markers will help you organize your evidence, so that the paper document can do so. Scale diagram of each crime scene using a tape measure and an axis axis and its axis and its baseline, its axis and its shape. A fingerprint is always something that we look for and we randomly search in common areas like doorknobs or padlocks in any place where any person would have touched something.
ResponderBorrarIf we enter or leave a room where we look for DNA in the areas where we usually look for fingerprints This is their biological fingerprint.
They will withdraw from the package in a sterile environment and the DNA test and there is a possibility that people get the DNA with a swab from a doorknob but there is our crime the laboratory has the technology to separate those DNA in the separated individuals
When the collected evidence is combined with other research works
Integrity is what shines when it comes to courts. Often, the defense will attempt to attack the integrity of the officer.
