Richmond-area police again bolstered patrols over the weekend after a sequence of shootings, including one fatal, that may tie to a long-standing feud between two neighborhood gangs.

The attacks began with a killing in front of a North Richmond corner store about 8:24 p.m. Friday. A shooting followed 10 minutes later in south Richmond, leaving a 50-year-old man wounded.

A black car found abandoned after the second attack also matches the description of one used in both shootings.

"It is the suspect vehicle" in the North Richmond shooting, Contra Costa sheriff's spokesman Jimmy Lee said.

Marquis Hamilton, 20, stood with a group of men at Fifth Street and Market Avenue when the car approached. Witnesses heard gunfire, and at least two rounds zinged through the doorway at Rancho Market & Deli, puncturing soda cans.

Hamilton stumbled inside and collapsed. A doctor pronounced him dead upon his arrival at Doctor's Medical Center in San Pablo.

Deputies working with a rough description of the car searched the area unsuccessfully. But, at 8:34 p.m., people in a similar car opened fire in the 400 block of Maine Avenue in south Richmond. The victim's injuries from that attack were not life-threatening, Richmond police said.

Officers searching the area found the car parked in the 300 block of Chanslor Avenue.

A shooting on Harbour Way in the Iron Triangle neighborhood followed on Saturday evening, wounding three. The city's acoustic gunshot detection system alerted officers at 5:22 p.m.

The attackers fired 27 rounds, and two people with gunshot wounds took themselves to the nearby Kaiser Permanente emergency room as officers responded. Police found a third wounded man in the 600 block of Harbour.

Neither law enforcement agency identified suspects or motives in the attacks. Richmond police added extra patrols on the weekend in anticipation of retaliation after the North Richmond homicide.
