Several investigations launched into shooting

Following San Mateo’s second fatal shooting by a police officer in 23 years, city and county officials have started at least five investigations into the incident and its aftermath.

The shooting at the Central County Mental Health Center at 3080 La Selva St. on Friday left one suspect, 43-year-old Hayward resident Adam Martinez, dead and a bystander injured. Martinez’s 17-year-old accomplice, his nephew, was arrested shortly thereafter.

In addition to criminal and officer investigations by the San Mateo Police Department, the San Mateo County District Attorney’s office will investigate the matter with help from the county forensics and coroner’s offices.

“We have several responsibilities as a law enforcement agency, we have a responsibility to investigate a crime, we have a responsibility to the San Mateo community,” said San Mateo police Capt. Kevin Raffaelli.

The two officers involved in the shooting are both on administrative leave while the incident is investigated and the department undergoes a “critical incident stress debriefing.”

The outside investigation by the DA’s office includes witness and officer interviews and information from the forensics and coroner’s departments, said John Warren, chief inspector for the Investigations Bureau.

The investigation, which followsany shooting involving an officer, seeks to determine whether the shooting was justified and whether the officer followed proper procedures.

The San Mateo Police Department will conduct a similar investigation, looking into both the discharging of a firearm and the use of force against a suspect. Both county and city investigations will determine whether the officers return to work.

“We need at least a verbal acknowledgment that the actions the officer took was justified,” Raffaelli said. “As long as we have a clear assurance that there were no violations and that the officer is ready to come back to work, we’ll bring them back.”
