What do they do?
A Forensic Toxicologist (FT) isolates and identifies any substances in the body that may have contributed to the crime, while a Forensic Chemist (FC) analyzes physical evidence and samples to assist in solving crimes.
What are their primary duties?
Forensic Toxicologists (FT) and Forensic Chemists (FC) deal with extremely meticulous work. For instance, FTs perform tests on samples collected by Forensic Pathologists, deal with highly sophisticated instruments, and make precise measurements for the overall success of the team. This work requires patience and concentration. FCs perform tests on physical examples, use tools, and measure very much like FTs. The main difference is that one is testing bodily samples and the other is testing physical evidence.
How have they been used to solve crimes?
Forensic Toxicology (FT) has been know to help solve some bizarre cases. For instance, fifty three year old Carol Hellar's death in 2003. She was a regular visitor in hospitals across America and was on several medications that could have easily killed her. However, FT helped us discover that her death was really a murder. Her husband had been slipping antifreeze into her drinks because he did not want to divorce her because he would lose his apartment.
