Crime Scene Analysis: Personal Experience

For the footprints, we compared the shoe details found at the scene with the shoe details of Alex Garcia, Doug Green, Erica Pidmont and Lucy Luffingwell. After searching through and comparing the shoe designs, we came under the conclusion that the footprint belonged to Anna herself, nobody else has the same shoe design as her own thus giving us the idea that it was not homicide. When we tested the pills, we made a chart testing multiple different indicators. We tested to see if the pills we had selected for the

There are four people of interest. Blood, hair, and fingerprints were all found at the scene as well

leading to the Alumni building, white powder near the blood pool, four shell casing on the south side of the porch, two bullet projectiles in the south side of the porch tree. The blood trail would have helped me to realize that the second person at the scene was hit with a bullet. Leading me to check the local hospital for any injuries from bullets. The white powder near the blood pool, would have been tested and found to be an illegal substance. With this information it would have been clear that there were two people at the scene partaking in a drug deal. The next piece of information is very important because up until this point it was assumed that only two people were at the scene that morning. The 4 shell casings and the two bullet projectiles in the tree to the south would prove that there were in fact three people at the scene that

After securing the outside perimeter, Crime Scene Investigators meticulously searched inside the dwelling; taking videos, photographs, and collecting over 1,000 fingerprints. The bedrooms had been ransacked but very few items of value had been taken. In fact, other items of value were left untouched such as cash (which was left in the open) and a safe, leading investigators to believe that robbery was not the motive. Among all of the evidence collected, two pieces of evidence

Due the victim being dead, the first step I would take in this case is a perimeter search. I would probably secure a larger area than I need because I can always shrink the perimeter once I begin processing. The second step I would do is once I found the perimeter, I would secure that boundary. And add police officers in various sides on the outside of the perimeter to help keep people away and sabotaging any evidence. In my head, I would do a walk though of the scene to determine the possible strategy or motive.

8.) Add one drop of iodine solution to wells C,F and I. Record any changes you observe. Caution - iodine solution is corrosive and poisonous. It can stain skin and clothing. Rinse any iodine spills with water.

A jewlery store was broken into and gold necklaces and diamond rings were found missing from a glass case that had been broken and glass was all over the ground. Drops of blood were found on the glass. A Crime Scene Reconstructionist was there to determine the entry point where the suspect walked in to the store in order to know where to look for evidence. A forensic pathologist

The book gives a general overview of the field of forensic science. The sections of the book include “The Scene of the Crime; Working the Scene--The Evidence; Working the Scene of the Body Human;

Since the time that the scientific science dramatization "CSI: Crime Scene Investigation" turned into a tremendous hit and generated its fans, reporters have been worried about what they instituted the "CSI Effect." The hypothesis behind the effect is that fans of the well-known show disguise misguided judgments about the law that they bring with them into the court as jurors. In this way, the trepidation is that the TV show is at last influencing the results of trials - and not in a great manner. Criminal justice researchers have started to study the inquiry of whether nationals who are called to serve on juries bring unreasonable desires and convictions to the court as a consequence of TV projects. The impact that these projects may have on the jurors, their desires, and their choices is known as the CSI effect.

Any moist or wet biological evidence (blood, body fluids, plants, etc.) like the lottery ticket on the counter with the blood smeared print on it should be collected wearing gloves it should then be placed in a clean unused paper container such an envelope, and or small bag and transported back to an evidence receiving area, it should then be taken out of the bag and allowed to air dry thoroughly. The Ninhydrin process should be applied to this piece of evidence to obtain noticeable prints.

By now the crime scene has been labeled a homicide and detectives have been dispatched to the scene. When the detectives arrive the lead officer will then provide a detailed crime scene briefing to the detective in charge of the scene. This briefing will be the only opportunity for the detective to receive the initial aspects of the crime scene prior to subsequent investigation. Since the crime scene and any/all evidence collected are the key factors in making a case, the crime scene must be documented as soon as possible including, appearance and condition of the scene upon arrival, lights on/off, shades up/down, doors, windows open/closed, any unusual smells, ice, liquids, weather conditions, temperature, and any personal items that may have been left behind. Once the lead detective has been briefed and evaluates the scene him/herself, he/she will then need to determine if consent to search and/or obtaining a search warrant is needed. The scene assessment allows the lead detective

Today, more than ever, the quality of evidence in criminal cases is scrutinized because of contamination. Contamination is the introduction of something that physically corrupts a substance at a crime scene that was not previously there; it comes in many forms and most often times comes from the humans who investigate a crime scene. It is imperative that prevention of cross-contamination is implemented when gathering evidence. Several of the more sensitive forensic techniques such as trace analysis, bloodspatter interpretation, and DNA comparison are not being used to their fullest potential. Items of physical crime scene evidence are not always visible to the naked eye and may be easily overlooked so deliberate and methodical approach to collection and preservation of evidence is essential. Prosecutors have lost cases due to crime scene contamination; this could be prevented by simple and productive behaviors. The U.S. Supreme Court, in a leading case on physical evidence, stated:

After doing their job in he crime scene, the evidence they took will be taken to the forensic scientist. Crime scene investigators will look at the photographs and connect their theories based on the crime that occurred. The forensic scientists will also examine the victim’s clothes, while the medical examiner will analyze the victim’s body for more clues and evidence that they may find and they will all be doing this in the crime lab. The things they may find could be hair, fiber, semen, blood, another person’s DNA, bruises and many more. After the forensic scientists

Like you see in the Crime scene investigation shows like CSI and Bones, there are many things that go into investigating shows a lot of those things happen but it takes much longer than forty or sixty minutes to solve the crime. While crime scene investigating is very serious job, collecting evidence at crime scenes requires education and knowing of what you're doing, requires hard work, and it can be difficult to perform this job.

Since most investigations start with very limited information, care and common sense are necessary to minimize the chances of destroying evidence. A plan of operation is developed and initiated from an initial walk through of the scene. The plan is to decide what evidence may be present, what evidence may be fragile and need to be collected as soon as possible. What resources, equipment, and assistance are necessary for the processing? Consideration of hazards or safety conditions may need to be addressed.
