The Ingham County Sheriff's Office has identified the man whose body was found in Holt last night as Samuel Decker, 18, of Leslie.
He was found on Calypso Road at 7:43 p.m. A witness said Decker was found lying next to a car.
CPR was given to the man and he was taken to the hospital, where he was pronounced dead.
The Sheriff's Office is treating this is a suspicious death because he was young, and so it being investigated as a homicide.
However, that is protocol used when a body is found, and police are not searching for a suspect.
They expect to have more details in a couple of weeks when an autopsy is completed.
