A 54-year-old man was discovered dead Friday evening in his vehicle that had crashed into a rural creek near Lone Star Lake.

According to an email from Douglas County Sheriff’s Office spokesman George Diepenbrock, the man’s family reported to deputies at 9 p.m. Friday they were concerned about his welfare, as they had last heard from him when he left in the morning to work at a field in the 1100 block of East 500 Road. After notifying deputies, family members found his vehicle had crashed into a creek.

When deputies arrived at the scene at about 9:30 p.m., they found the man dead in his vehicle, which had left a field road, crashed through a fence and entered the creek, Diepenbrock reports. Deputies and detectives continue to investigate the cause of the crash.
