Detective Sergeant Leroy Gross has been with the Jamestown Police Department since October of 1989. Det. Gross worked uniformed patrol from 1989 to 1994 when he was appointed to the Stutsman County Narcotics Task Force. In 1998 he was transferred to the Detective Division of the Jamestown Police Department. He rose through the ranks and is our second most experienced active detective. Detective Gross has specialized training in fraud and financial crimes, dangerous drugs, fire investigation, SWAT, computer crimes and crimes against children, crimes against the elderly, and human trafficking. He has a passion for, and dedicates time to teaching citizens how to detect and prevent being the victim of scams. Recently Det. Gross worked a case that started as a simple warrant arrest. That arrest lead him to question a relationship between the suspect and her boyfriend. After winning the trust of the warrant suspect and some further investigation, it turned out this was a human trafficking case. Ultimately the warrant was cleared. However, instead of taking the warrant suspect to jail, Det. Gross was able to separate the suspect-turned-victim, from her a human trafficking situation.
