San Mateo care-home facility worker kills colleague, self

SAN MATEO, Calif. - A worker at a San Mateo residential care home shot and killed a fellow employee before taking his own life, authorities and the facility's administrator said.

The shooting happened at a home near the corner of Pierce Street and Speers Avenue at about 7:20 a.m.

The administrator of the facility told KTVU that an employee opened fire, killing another worker with whom he had been having a feud for several weeks. The nature of their dispute wasn't known.

None of the three residents who live at the home were injured. 

Shortly after the shooting, police and a SWAT team surrounded the suspect's home on Marina Court about a mile away.

After a four-hour standoff, the suspect was found dead inside, the victim of a suicide, police said. His wife came out of the home without incident. 

This death follows a homicide reported on Oct. 30, where a 30-year-old man was killed in the 1600 block of Eleanor Drive, where an injured young child was also found in the driveway. 

In that case, too, detectives said that at this point they believe this was a "targeted and isolated incident."
