The seven teens had been feuding with Barreto's teenage stepson Benjamin "Benny" Torres for months in person and on Facebook. Two of Barreto's stepsons and one of the teens who survived the shooting attend Mariana Bracetti Academy Charter School, where the day after the shooting Mayor Nutter and other officials visited to speak out against retaliatory violence.
The group of teens drove to Barreto's house that night so one of them could fight Benjamin, but instead encountered Barreto, authorities said.
After being arrested, Barreto told police in a statement that he was smoking a cigarette on the front porch when he first saw the Toyota slow down in front of the house, according to homicide Detective Jeffrey Burke, who read Barreto's statement in court.
After the car drove in front of the house a second time, Barreto said, it slowed, one of the occupants said something and Barreto went inside the house.
When he learned from Benny what the teens' intentions were, Barreto said, he got a gun, went out back and began shooting at the car, which by then was parked behind the house.
Defense attorney Jack McMahon said his client acted to protect his family against a violent gang of youths who called themselves the Kick Ass Boys.
"He's in his own home just trying to watch television, and these kids bring it to him," McMahon said after the hearing. "It comes a point and time where you gotta take action."
Assistant District Attorney Jude Conroy said that none of the victims was armed and that each was shot from behind while the car was driving away.
"These kids were in full flight mode when this man began to fire," he said. "They went there for a one-on-one fistfight. Nobody had a weapon."
