HAYWARD -- Joshua Alford, the target of the Oct. 2, 2011, San Leandro warehouse party shooting that left three dead and three wounded, was shot dead that night because he associated with a group that got into a beef with the accused killers at a San Francisco party a couple months earlier, according to trial testimony Monday from an Oakland man who is taking a plea deal in the triple-murder case.

Alford, a 23-year-old Oakland resident, likely never saw it coming.

"He didn't do nothing. He didn't look our way. He didn't know we were in there," Stanley Leon Turner said, recalling how he and his friends watched Alford at a tattoo party that immediately preceded the shooting at Alvarado Street and Aladdin Avenue. "Really he was a nobody, nobody to worry about."

Alford and six others were sitting in an SUV in the parking lot outside the party when they were fired upon. Along with Ashford, 19-year-old San Franciscan Shanice Kiel and 16-year-old Leneasha Northington, of San Leandro, were killed.

Turner has been offered a three-year sentence and his own murder charges dismissed if he pleads guilty to being an accessory to the killings and testifies truthfully against his former co-defendants. Paul Arthur Stevenson, 22, of Oakland; Anthony Alvin Perry II, 23, of Oakland; and Aaron Isaiah Stewart, 21, of Fairfield -- alleged members of an East Bay street gang -- each face life in prison without the possibility of parole if convicted as charged.

Turner said Alford was hanging out with a rival clique at the San Francisco party when someone from the group bumped into Stevenson, or vice versa. He said Alford did not participate in the ensuing confrontation in which another person from Alford's clique flashed a gun, and Turner and his friend drew their own firearms.

On the night of the tattoo party, Turner said he and the same friend passed their guns on to Stevenson to get the weapons into the party. Afterward, Turner testified, they were sitting in his car ready to leave when they heard gunshots. Thinking the shots are directed at them, he drives off and picks up a running Stewart.

Stewart told them that "they just got on some (expletive)" and that the gun he was using, Turner's own 9 mm, jammed, Turner testified.

The East Bay street gang and their friends then convened outside a house in Oakland, where Perry told everyone that he had "emptied his clip," Turner said. Stevenson arrived later and told the group "he was shooting his gun too," Turner said.

Some of the men present were angry to learn that some women had been shot, according to Turner.

"That got everyone stirred up," Turner said. "We were like, we didn't know there were any females in there."

"Had those girls done anything to you guys?" prosecutor Jimmie Wilson asked.

"No, man. No," Turner said.
