S.F. slaying:

The victim of a shooting that led to a 15hour standoff was the mother of the alleged gunman.

A woman whose killing in San Francisco prompted a tense 15-hour standoff between the suspect and police was identified Thursday as the 76-year-old mother of the alleged gunman, who officials said ended the crisis by turning the gun on himself.

Martha Alfaro was shot in the back by her 52-year-old son, who remains hospitalized, at about 11:45 p.m. Sunday on 15th Street near Corona Heights Park, authorities said.

Officers responding to reports of shots fired were able to extract her from the scene and transport her to San Francisco General Hospital, where she died.

Her son, whose name has not been released, barricaded himself inside the home, still armed with the handgun used in his mother’s death, police said.

Officers from the crisis-hostage negotiation team worked to talk the son into surrendering peacefully, a process that continued into Monday afternoon.

Police said he stumbled out of the home at 2:45 p.m., bleeding from a self-inflicted gunshot wound to the chest. Neighbors said they heard two shots just before the man emerged.

He was taken to a hospital with injuries

that were considered life-threatening. His condition Thursday was not known.

After the man was in custody, a shelter-inplace order for nearby blocks remained in effect as a bomb squad swept the house for possible explosives, but officers found no other threats.

Police said no shots were fired by San Francisco officers. Officials have not discussed possible motives in the case.

Anyone with more information was urged to call the San Francisco Police Department anonymous tip line at (415) 575-4444, or text a tip to TIP411 with “SFPD” at the beginning of the message.
