Irvine police responding to reports of gunshots heard at the Trabuco Grove shopping center Wednesday found a dead man slumped behind the wheel of his parked white Lexus.
The incident was reported at 4:40 p.m. behind an Albertsons supermarket at Jeffrey and Trabuco roads, said Lt. John Hare, a spokesman for the Irvine Police Department.
Police said it was unclear whether the fatal bullet was fired by an assailant or was self-inflicted, and officers did not know how many shots were fired.
"A subject was seen leaving the area shortly after the incident, though the description was vague -- someone in a black, hooded sweatshirt walking out of the area where the gunshot was heard," Hare said.
Detectives were on the scene interviewing witnesses and bloodhounds were combing the area for the person seen leaving, Hare said.
