This week, law enforcement officers trained at the Gwinnett County Police Department to strengthen their crime investigation skills through a shooting reconstruction course.

The course was part of the kickoff for the Forensic Training Source, a new non-profit organization based in Cumming that is dedicated to law enforcement training nationwide. The week-long class covered a number of scenarios including gunshot residue, identifying bullet marks, motor vehicles as a target surface and report writing.

FTS owner Nathan Lefebvre said author Patricia Cornwell has been a tremendous help to the first group of trainees; known for her Kay Scarpetta crime novels, Cornwell donated scholarships to all 27 participants in the class.

While the officers come from different law enforcement groups in Tennessee, Florida and Kentucky, there are also students from local departments, too, including Lawrenceville Police, Gwinnett County Police, Winder Police, Forsyth County Sheriff's Office, Milton Police, Roswell Police and Johns Creek Police.

Watch the video above to see what the officers' training was like.
