A man was fatally shot in the chest in the parking lot of a market near the Berkeley Marina after an apparent exchange of gunfire between two groups that had planned to meet there, police said Wednesday.

The victim was found by Berkeley police about 8 p.m. Tuesday behind the Sea Breeze Market at the corner of University Avenue and West Frontage Road, just off Interstate 80. Officers found shell casings from more than one gun nearby.

The investigation was turned over to East Bay Regional Park District police because the market is on park property. The victim’s name has not been released, and police have made no arrests.

Park district police Sgt. Tyrone Davis said a motive was not yet known. He said one of the groups involved in the shooting had contacted the other to set up a meeting, but it was unclear which group the dead man belonged to.

The slaying happened 10 days after a man was arrested on suspicion of fatally stabbing 78-year-old Warner Willis in West Oakland and committing a series of carjackings, including one outside the Sea Breeze Market.

Berkeley police arrested the suspect, 26-year-old Bennie Williams, after he crashed a car near Ashby Avenue.
