The leader of a street gang was convicted by a federal jury Tuesday in connection with the shooting death of a college student, who the killers mistakenly believed was a rival, officials said. Danilo "Triste" Velasquez and two fellow MS-13 gang members blocked the way of a car carrying four people near the Daly City BART station before opening fire with semi-automatic handguns, officials said. When the shooting ended on Feb. 19, 2009, Moises Frias, 21, was dead and two others were wounded. Velasquez was convicted of three counts of conspiracy and a gun charge in San Francisco federal court, according to a statement from U.S. Attorney Melinda Haag. When he is sentenced Feb. 14, Velasquez faces a mandatory term of 10 years behind bars. Velasquez and his associates targeted the car because one of Frias' companions wore a red sweater and another a red-and-white San Francisco 49ers hat. Red is the color claimed by the shooters' rivals, officials said. None of the victims had any ties to street gangs. "In a hail of gunfire, Mr. Velasquez and his co-conspirators killed and wounded four unarmed individuals -- all in the name of MS-13," said Assistant Attorney General Lanny Breuer. Co-defendant and fellow MS-13 member, Luis "Killer" Herrera already has pleaded guilty to related charges. He faces a 35-year mandatory term Advertisement when sentenced Jan. 24. Jaime Balam, the other shooting suspect, remains at-large. Federal prosecutors say the killing was part of a string of shootings carried out by or at the order of Velasquez. He assumed leadership after a number of gang leaders were indicted in 2008. The victims in the other shootings survived their wounds. Prosecutors say the only reason more people didn't die in the attack that left Frias dead was because Velasquez's gun repeatedly jammed. Witnesses testified at the four-week trial that Frias begged for his life before he was shot nine times by Balam, including a wound to the head.
