Forensic Science

Yes, leaving the scene of an accident, especially if there are injuries or significant property damage, is considered a crime in most jurisdictions. It is important to stay at the scene, check for injuries, and report the accident to authorities.

Criminals wear gloves to avoid leaving fingerprints, as fingerprints are a common way to link a person to a crime scene. However, even with gloves, criminals can still leave other trace evidence like DNA, fibers, or shoe prints that can potentially be used to track them down.

The most common type of assessment conducted by forensic psychologists for criminal courts is assessments of competency to stand trial. This assessment evaluates whether the individual understands the legal proceedings and is able to participate in their defense.

Teeth impressions can help solve a crime by providing an imprint of a suspect’s teeth that can be compared to bite marks found at a crime scene. Forensic odontologists can analyze these impressions to determine if there is a match, which can be used as evidence in a criminal investigation. This technique can link a suspect to the crime scene or provide valuable information in cases where bite marks are present.

At the Black Dahlia crime scene, the body of Elizabeth Short was found severed in two at the waist. Her face was slashed from the corners of her mouth towards her ears, creating an eerie smile (often referred to as the Glasgow smile). Additionally, some reports suggest that her body was drained of blood, washed clean, and posed in a vacant lot in Los Angeles.

Sketches of a crime scene typically record the placement of evidence, features of the environment, and the position of victims or suspects. They provide a visual representation to aid investigators in understanding the layout and details of the scene. These sketches are used to accurately document and analyze the scene for investigative purposes.

The sketch of the crime scene should include the dimensions and layout of the location, the position of evidence and objects, and any relevant details such as blood spatter patterns or bullet casings. It should also note the location of doors, windows, and other points of entry or exit.

A crime scene in forensic science is the location where a criminal act has taken place and where forensic investigators collect and analyze evidence to reconstruct what happened. It is crucial for preserving and documenting evidence that can help solve the crime and identify suspects. Crime scene analysis is a fundamental part of forensic investigations.

Police use observation skills to gather information, assess situations, and identify potential suspects or evidence. Observation helps them notice details that may be critical to solving a crime, such as identifying witnesses, suspect behavior, or important physical evidence at a crime scene. By keenly observing their surroundings, police can make informed decisions and piece together the facts of a case.

A coroner at a crime scene assesses the body to determine the cause of death. They collect evidence, such as medical history and witness statements, to aid in their investigation. They may also take samples for toxicology tests and document injuries or wounds on the body.

A rough crime scene sketch is typically done before evidence is collected. This preliminary sketch helps document the layout of the scene, including the location of items like weapons, bodies, and other important details for investigative purposes. It is not meant to be precise, but rather to provide a general overview of the scene.

Forensic scientists analyze evidence collected from crime scenes using scientific methods like DNA analysis, fingerprinting, ballistics, and toxicology to provide crucial information to investigators. By examining and interpreting this evidence, they can help identify suspects, establish timelines, and reconstruct events to assist law enforcement in solving crimes and bringing perpetrators to justice. Additionally, forensic scientists may testify in court as expert witnesses to present their findings and help strengthen the prosecution's case.

An evidence collection unit is trained in proper evidence handling techniques, ensuring that evidence is not contaminated or mishandled. They follow established protocols to document and collect evidence systematically, increasing the chances of admissible evidence in court. This specialized unit also frees up detectives to focus on other aspects of the investigation, increasing efficiency and effectiveness in solving crimes.

Some popular forensic crime shows on TV include "CSI: Crime Scene Investigation," "Forensic Files," "Bones," and "Mindhunter." These shows typically focus on solving crimes using scientific methods and forensic evidence.

Locard's principle of exchange is important in criminal investigation because it states that every contact leaves a trace, allowing investigators to link suspects, victims, and crime scenes through the transfer of evidence. By identifying and analyzing these trace materials, investigators can reconstruct events, establish connections, and ultimately solve crimes. This principle emphasizes the significance of collecting, preserving, and analyzing physical evidence in criminal investigations.

Forensic entomologists study insects that colonize decomposing human remains to estimate the time of death, help determine location of death, and provide other valuable evidence. By analyzing the insect activity on a body, entomologists can assist in solving crimes by providing crucial information to investigators.

The exact time cannot be said but since the finger print results are good only for a year you can expect to get the green card within a year. So its important to do finger printing as close a date as possible and have the valid results handy during the green card interview process.

Hair found at a crime scene contains DNA, which can be compared to a suspect's or victim's DNA to establish a link. Hair also has unique characteristics like color, length, and treatment, which can be used as evidence in investigations. Analyzing hair evidence can help to identify individuals present at the crime scene.

Some advantages of the criminal justice system in the Philippines compared to the US include a simpler legal system with less bureaucracy, lower costs for legal proceedings, and a focus on restorative justice. Additionally, the Philippine system places a higher emphasis on community involvement and rehabilitation of offenders.

The Ari Squire case was inspired by the episode titled "Sealed with a Kiss" in Season 3 of Forensic Files. In this episode, the forensic evidence played a crucial role in solving the case involving the murder of Ari Squire.

No, forensic techniques can also be used in other areas such as archaeology, anthropology, and environmental science to analyze and interpret evidence. The principles of forensic science, such as evidence collection, analysis, and interpretation, can be applied to a variety of fields beyond criminal investigations.

When a witness is taken back to the crime scene, it is known as a witness walkthrough or a witness reenactment. This can help refresh the witness's memory and provide investigators with valuable insights into the sequence of events.

No, a DUI arrest or conviction does not typically show up on a fingerprint check. Fingerprint checks are used to identify individuals based on their unique fingerprint patterns, not to access their criminal history. DUI arrests or convictions would appear on a criminal background check conducted by law enforcement agencies.

People hand write things differently so say the murder left a note saying i killed this guy. it was hand written and left no genetic evidence so they they find out who wrote it by looking at different peoples handwriting.

The consequences for a court case if a crime scene is not secured properly is bad. There is a less chance that you might have got the right evidence. The evidence might have been damaged as neighbors could have walked in and touch things or the rain might have washed the footprint outside the garden
