JACKSONVILLE, Fla. -

Homicide detectives are investigating after a man was found dead Sunday morning in a car parked on Coronet Lane.

The man, described as Hispanic and between 20 and 30 years old, was found by the car's owner about 10 a.m. The car owner says he doesn't know the man or why the man was in his car.

The car's owner did say he had left his car unlocked, and that he sometimes does. 

Jacksonville Sheriff's Office detectives say there were no obvious signs of trauma, aside from blood in the man's nose and mouth. They say they are waiting for the medical examiner to remove the body to see if there is trauma and if foul play was involved.
