UPDATE, 1:30 p.m. Chantry Flats has reopened, and police have taken a man accused of attempted murder into custody.
Patrick Anthony Gonzalez allegedly tried to kill himself and a female companion by driving off a cliff along Chantry Flats Road on Saturday night.
When the attempt failed, Gonzalez reportedly ran away and broke into a home at the Santa Anita Dam. The residents escaped unscathed, and warned officers about a loaded firearm in the home.
A standoff ensued when Gonzalez allegedly failed to comply with officers' orders to exit the home.
A Los Angeles County Sheriff's Department SWAT team entered the home before noon Sunday and took Gonzalez into custody. Police took Gonzalez to the hospital with unspecified injuries but his female companion was uninjured.
