Guillermo David Gonzalez, 25, has been sentenced to two consecutive terms of life in prison without the possibility of parole, plus 50 years to life, for the September 2024 shooting deaths of Junior Alastre, 23, and Osnaider Silveira, 28, in the Barrio Logan neighborhood of San Diego. Gonzalez was convicted of first-degree murder and firearm allegations.

Why it matters

The double homicide in Barrio Logan, a predominantly Latino neighborhood, highlights ongoing concerns about gun violence and public safety in San Diego. The victims were recent Venezuelan immigrants, raising questions about the challenges faced by new arrivals to the U.S.

The details

According to prosecutors, Gonzalez first opened fire on Alastre, who was sitting in a parked Mitsubishi, then moved to a nearby parked Kia and shot Silveira multiple times, even pulling his lifeless body from the car and firing additional shots. The shooting was captured on surveillance footage. Gonzalez then stole Silveira's car but was arrested the next day in Rosemead, Los Angeles County. A motive for the killings remains unclear.

  • The shooting occurred on September 14, 2024, just after 9:30 p.m.

— Steven E. Stone, Superior Court Judge

“The killings were nothing less than executions of unarmed, innocent victims.”

— Steven E. Stone, Superior Court Judge
