At about 5:10 p.m., police received reports of possible shots fired in the 2800 block of Milvia Street, just west of Adeline and Russell streets, police Sgt. Mary Kusmiss said.
Berkeley police found the man slumped over the wheel of a parked car in that block.
Paramedics responded and tried to revive the man, but he was pronounced dead at the scene, Kusmiss said.
The man was the city's third homicide victim of the year.
