Kansas City police investigators have opened a homicide investigation into what police originally thought was a hit-and-run death after finding a man in the street covered in blood.

Police say in a news release that officers were called to the area of Linwood and Elmwood avenues around 3 a.m. Thursday and found the man badly injured. The man was rushed to a hospital, where he later died.

At the hospital, it was determined the man's injuries were not from a hit-and-run crash, and police declared his death a homicide. Police have not released the victim's name.

Officials are offering a $25,000 reward for any information leading to an arrest.
