Forensic Science

Forensic Science is a teamwork event that provides HOSA members with the opportunity to work as a team to apply their knowledge and skills in creating a solution to a forensic science-related problem. This competitive event consists of 2 rounds and each team consists of 2 people. Round One is a written test and will evaluate the team’s understanding of forensic science. The test score from Round One will be used to qualify the team for Round Two. In Round Two, teams will be given a case study to analyze that may include physical evidence and written information such as police reports and an autopsy. Teams will have six (6) minutes to view the “crime scene” and thirty (30) minutes to write their conclusions with supporting evidence. This event aims to inspire members to be proactive future health professionals and critically examine elements of a forensic case.

The round one test is during the online testing window of February 24- March 7, 2025.

Forensic science sample case study.

Police Report by Officer Gold:

At 0734 hours a 911 call was placed from the residence of Fred Mars. He states that a guest in his home, Red Fisher, is on the living room floor and unresponsive.

Upon arrival by the EMS and Officers Gold and Freeman at 0739 hours, the decedent was found on the floor....

On 6/25/2016, the decedent reportedly went to a party at the home of Fred Mars at 3400 Main Street. It is reported that the decedent was depressed and angry at having been fired from his job that day, and was allegedly using heroin and cocaine, as well as some other drugs. Sometime between 2300 and 2400 hours, Fred Mars and the decedent had a physical altercation, and according to Mars “He collapsed. I figured I knocked him out, or he passed out. I wasn’t sure which. I rolled him over onto his back and he didn’t wake up. I figured he would be angry when he woke up so I left him there and went to my girlfriend’s house. When I got home after seven this morning, Red was still on the floor in the same position I left him, and wouldn’t wake up. That’s when I called 911.”
