A Williamson County man faces DUI charges after a deadly crash in June. Reports from WSIL say the Jefferson County State’s Attorney says a urine test showed Cole Stevens had cocaine in his system at the time of the crash. Police reports say Stevens crossed the median on Interstate 57 and hit another car head on killing 18 year old Emma Caserotti. Her passenger 18 year old Tristen Sharp, suffered major injuries. Prosecutors are still waiting for blood work and say that there is a possibility of more charges to be filed.
