While the investigation into the shooting is still in its early stages, police said interviews with witnesses and family members of Rivera led detectives to believe he was seeking confrontation.
“We are learning that the suspect had estranged himself from his family, was drinking heavily and had made comments regarding suicidal ideations,” Joseph said. “By all accounts, we believe the suspect was determined to have an armed confrontation with police and unfortunately shot a bystander during his self-created melee.”
Before police arrived in the area, a man who police said was shot by Rivera had already been transported to a hospital. Joseph said the two men don’t appear to have a known connection, and it’s still unclear what happened between the two of them before the shooting.
At a press conference Monday afternoon, Joseph said the four officers who shot at Rivera all had their body-worn cameras activated at the time of the shooting, and all are crisis intervention trained.
The officers, who were not identified by police, have between three and seven years of experience as police officers, Joseph said.
San José Mayor Matt Mahan lauded officers for the “incredible courage and professionalism” displayed during the incident.
“I believe that the reason that this was not a much worse tragedy than it already is, is because our officers responded quickly and courageously and did what they needed to do to ensure the safety of others who were there,” Mahan said during the press conference.
“We’re praying for the victim,” he said, “and just grateful that there aren’t other victims.”
The shooting marks the fourth time this year a San José Police Department officer, or officers, have fired their guns on duty — and the first time this year the shooting resulted in a death, police said.
The incident is being investigated by the department’s homicide unit and the Santa Clara County District Attorney’s Office and is being monitored by the San José Police Department’s Internal Affairs Unit, the City Attorney’s Office and the office of the Independent Police Auditor for the city.
