Someone called 911 after seeing a body in the road at Boston and Market around 10:00 pm Monday.
The man, identified as 42-year-old Brian D. Turner, was rushed to the hospital where he was pronounced dead.
At first, crews thought he was struck and killed by a vehicle, but they've determined that was not the case. Now, police are trying to figure out why Turner was in the area and what happened to him.
The coroner is working to determine the cause of death. He had some injuries to his face, but police don't think those contributed to his death.
Anyone with information is asked to contact police at (316) 268-4181.
