A man shot his coworker Monday morning in what San Mateo police are describing as a murder-suicide involving coworkers.
At about 7:20 a.m., officers responded to a report of a shooting at a care home in the 1700 block of Pierce Street.
Upon arrival, officers discovered a deceased 42-year-old man who was shot multiple times. Employees at the scene told officers the suspect is a 48-year-old coworker of the victim.
“The motive appears to have been over a dating relationship they both shared with a woman,” police said. “Statements provided on-scene enabled officers to identify the suspect and his current location within minutes.”
Soon after, officers including members of a SWAT team and crisis negotiators went to the suspect’s location at a home in the 1600 block of Marina Court. They set up a perimeter, evacuated nearby residences and learned the suspect’s wife was voluntary inside the home.
“Over the course of 4-hours, negotiators remained in contact with the wife and suspect, and worked diligently to ensure a peaceful surrender,” police said
At 12:12 p.m., officers heard the sound of one gunshot while on the phone with the homicide suspect. His wife exited the home shortly thereafter, and police used to a robot to enter the suspect’s room, where he was found deceased on the second story of the home from a self-inflicted gunshot wound, police said.
