Peter Mootz/Daily Journal San Mateo police say the body of a middle-aged man who was stabbed to death was found at on the property of All American Self Storage in San Mateo yesterday afternoon.

A man was stabbed to death at a self-storage facility in San Mateo early yesterday afternoon, according to police.

It appears the victim was specifically a target and that the stabbing did not appear to be a random act, said San Mateo police Sgt. David Norris.

Police responded to All American Self Storage on East Third Avenue and Detroit Drive at about 1:30 p.m. and found the victim dead.

Norris described the victim as middle-aged but offered few other details about the stabbing.

The victim’s name was not released by the San Mateo County Coroner’s Office pending notification of next of kin.

Police blocked off the storage facility for several hours yesterday as investigators interviewed potential witnesses.

Deputy Police Chief Mike Callagy was on the scene conducting interviews himself about two hours after police were first called to the scene.

Storage facility customers on scene at the time of the police activity were forced to abandon their vehicles inside the perimeter of the complex and wait out on the street until after police concluded their investigation.

None of the customers, however, had any idea what led to the man’s stabbing. It is the first homicide in San Mateo this year although police were involved in an officer-involved shooting earlier this year when an erratic man was killed in front of his home.

Outside agencies, including Belmont and Foster City police and the California Highway Patrol, were brought in to assist in yesterday’s investigation, Norris said.

District Attorney’s Office officials were also on scene.

Police offered no suspect information yesterday.
