Alvin Baja Luis, 55, of San Francisco, was arrested this morning and is being held without bail in San Mateo County Jail, San Mateo County District Attorney Steve Wagstaffe said.
Luis is suspected of going to a home at 521 Spruce Ave. at about 7:50 p.m. and confronting several family members regarding an ongoing disagreement, according to South San Francisco police.
During the confrontation, Luis allegedly pulled out two handguns and ordered his family into an area of the home, police said.
While one family member tried to negotiate with him, the others escaped out a window.
Luis allegedly caught them during the escape and fired one shot, wounding his sister in the hand, police said.
The other family members escaped unharmed, police said. Luis fled after the shooting.
The suspect was booked into jail on multiple felony charges, including one count of attempted murder, seven counts of false imprisonment and seven counts of making threats, Wagstaffe said. Luis is scheduled to be arraigned in Redwood City on Tuesday.
