A 19-year-old arrested in the gang related killings of two men in the Mission District Sunday has been charged in only one of their deaths.
Andres Siordia, who will be arraigned this morning in San Francisco Superior Court, faces a murder charge for the killing of San Francisco resident Francisco Pena, 41, and the attempted murder of another man. Both charges include enhancements for the use of a firearm during the commission of the crimes.
Pena and Francisco Cornejo, 26, were killed and a third man was wounded Sunday after a fistfight turned into a triple shooting at a Papa Potrero’s Pizza at 24th Street and Potrero Avenue.
Police arrested Siordia minutes later, along with a 16-year-old suspect, who has not yet been charged.
According to the district attorney’s office, Cornejo’s killing remains under investigation and no charges have been filed yet.
