A 30-year-old gang member has been convicted of killing five people, including two men in Santa Monica in 2005, according to the Los Angeles County District Attorney’s Office.

William Vasquez, a member of the 18th Street gang, was found guilty by jurors Dec. 9 in the first-degree murders of five victims between 2002 and 2005, district attorney spokeswoman Shiara Davila said. Two of the victims included Jonathan Hernandez and Hector Bonilla, who were fatally shot during a private party at the Moose Lodge in Santa Monica in March 2005.

Jurors found true special circumstance allegations of multiple murders and that the defendant was an active participant in a criminal street gang, Davila said.

Vasquez was additionally convicted of one count of attempted murder and two counts of assault with a semiautomatic firearm, with gang and gun allegations found true, according to the district attorney.

An allegation that the defendant personally used a firearm for one of the murders was found not true.

Jose Mojarro and Erick Nunez were previously found guilty by jurors in the murders of Hernandez and Bonilla and sentenced to life in prison without the possibility of parole.
