After their arrest, the 15-year-old told police that the trio had been targeting homeless people for the past year, according to a criminal complaint. A man at the house where police found the trio Saturday declined to comment on Monday as he watched a steady stream of reporters and photographers visit a corner lot where neighbors said the homeless regularly camped without bothering anyone. According to a criminal complaint, he told police they lifted them over their heads and took turns dropping them on the men's faces. On Friday night, the 15-year-old said he was angry about breaking up with his girlfriend, and the three returned from a party and covered their faces with black T-shirts and went out to look for someone to beat up and possibly rob, the criminal complaint says. The district attorney's office said the younger suspects were charged as serious youthful offenders, meaning they could be tried in adult court.
