SAN BERNARDINO – Three men charged with trying to kill two San Bernardino police officers during a shootout a year ago pleaded guilty Friday in Superior Court. Jonathan Contreras, 20, Orlando Cruz, 24, and Gonzalo Medina, 22, pleaded guilty to one count of assault on a peace officer and an allegation of furnishing a firearm. Judge David Mazurek sentenced each defendant to 15 years in state prison. The charges stem from an August 22, 2014 incident that occurred when Officer Gabriel Garcia and his trainee partner, Officer Marcus Pesquera, approached the three defendants and a fourth man, Alex Alvarado. Alvarado began shooting at the approaching officers-leaving Officer Garcia critically wounded. Alvarado, who was identified by police as the shooter, was shot by Officer Pesquera. Alvarado later died. San Bernardino Police Chief Burguan said. "I am very proud of the men and women of the organization that investigated this heinous crime on that day, and I am pleased to see the progress that Officer Garcia has made. I am also happy to see Officer Pesquera receive the recognition that he deserves for his actions that day. I would like to thank DA Ramos and the attorneys from his office that worked on this case. Today is a milestone in that we can continue to move forward knowing that justice has been done."
