Question

Describe how forensics scientists use digital resources to store information and help determine if a weapon was used in multiple crimes.

When analyzing a bullet, what do forensic scientists look for? How can a bullet be matched to the gun it was fired from?
If a tool mark is found at the scene, how would forensic scientists go about collecting, storing and analyzing it? Why can tool marks be difficult to recreate?
State 2-3 ways that medical examiners determine time of death. Explain the procedures and what information can be discovered in the process. How is Bill Bass’ Body Farm helpful in this research?
What are the three categories of data that forensic scientists collect during an autopsy? Invent a scenario where a forensic scientist is examining a corpse. Things to consider: What might they discover and how could this information contribute to an investigation?

Answer 1

Forensic scientists use digital resources, microscopic examination, and DNA analysis to link evidence such as bullets and tool marks to criminal activities. They also determine time of death and contribute to autopsies. The Body Farm provides critical research data for understanding human decomposition.

Step-by-step explanation:

Forensic Scientists and Crime Scene Investigation

Forensic scientists are key in unraveling the details of crimes by examining various types of evidence. Using digital resources, they store information to help determine if a weapon was used in multiple crimes. When analyzing a bullet, forensic scientists look for unique markings left by the barrel of a gun, known as the ballistic fingerprint.

Through comparison of these marks, a bullet can be matched to the gun it was fired from. Tool marks at a crime scene are collected and analyzed similarly, but can be challenging to recreate due to the uniqueness and variation in hand pressure and angles during the criminal act.

Medical examiners determine the time of death by observing body temperature, rigor mortis, and insect activity. Bill Bass' Body Farm is a research facility that studies human decomposition in various conditions, providing invaluable data for understanding the postmortem interval. During an autopsy, forensic scientists collect data on pathological, physiological, and chemical characteristics.

In a hypothetical scenario, a forensic scientist examining a corpse might determine the victim's identity, cause of death, and potential time of death, which are all pivotal in advancing a criminal investigation.
