Police said a suspect wearing a dark hoodie fired a shot at the victim before fleeing in a dark-colored, four-door sedan traveling eastbound on Waite Drive.
"The relationship between the suspect and the victim is unknown, but investigators do not believe this was a random act of violence," the department said.
The victim's identity was being withheld pending notification of next of kin, and no further information was immediately available.
For several hours following the discovery, Waite Drive was shut down in both directions between Violet Street and Massachusetts Avenue, police said.
Authorities urged anyone with information regarding the shooting to call the police at 619-667-1400 or call Crime Stoppers at 888-580-TIPS.
