SAN JOSE >> Four people were arrested on suspicion of shooting at two San Jose plainclothes police officers last week, according to a department press release.

One of the officers returned fire after they were fired upon, but no injuries were reported.

Around 10:38 p.m. on Jan. 20, the plainclothes officers were at a red light at the intersection of McLaughlin Avenue and McLaughlin Court, in an unmarked police car, when four people in a car pulled up alongside them. According to police, the suspects indicated that they were armed and appeared to be “provoking a confrontation.”

When the signal changed, the suspects drove through the intersection while the officers pulled over and parked along the intersection of Melbourne Boulevard and McLaughlin Avenue.

A few moments later, the suspect vehicle turned around and drove towards the officers, who were calling for an assist from uniformed officers. Police said that at least one suspect opened fire, striking the police car multiple times. One officer left the car and returned fire. The suspects then sped away from the scene; the police officers were unable to follow due to the car being damaged by the gunfire.

On Thursday, SJPD Homicide Unit detectives identified the suspects and obtained arrest warrants and search warrants for their homes.

That same day, Santa Clara resident Gabriel Olmos, 21, was arrested in Merced, San Jose resident Robert Cesena, 37, was arrested in San Jose and San Jose resident Emilio Macias, 22, was arrested in San Francisco. San Jose resident Edward Ruiz, 21, was arrested in Gilroy on Saturday.

All four were arrested on suspicion of multiple crimes including attempted murder and taken to the Santa Clara County Main Jail. They are all being held without bail.

“These suspects tried to take a life, and now they’ve lost their freedom,” said San José Mayor Matt Mahan. “I’m grateful to our police department for proving once again that with crime comes consequence in San José.”

Police said the investigation involved the entire SJPD Bureau of Investigations and Bureau of Field operations and the Santa Clara County District Attorney’s Office.

“Last week I said all those responsible will be held to answer for this despicable act of violence, and I stood by my word,” stated SJPD Chief of Police Paul Joseph, “Thanks to the quick actions and around-the-clock investigative efforts of our Homicide Detectives, and our Gang Investigations Unit Detectives and Special Operations who worked tirelessly on this case, we now have the suspects in custody, awaiting their fate from the justice system. We do not take gun violence lightly, especially when it involves an assault on our Officers.”
