A woman barricaded inside a senior living apartment where deputies reported hearing shots fired Friday afternoon prompted an hours-long standoff and a building evacuation before she was taken into custody. Deputies on their way to a building in Castaic on Friday afternoon, carrying out a “welfare check” on the woman, reported hearing gunshots from the building as they approached, said Sgt. Wayne Waterman of the Santa Clarita Valley Sheriff’s Station. Sheriff’s officials from a crisis negotiation team were at the senior living complex attempting to resolve the situation around 8 p.m. Deputies with the department’s Special Enforcement Bureau managed to take the woman into custody without incident around 11 p.m., according to SCV Sheriff’s Station officials, who said no further information was available as of 11:10 p.m. Shortly after 4 p.m., deputies at the Castaic Senior Village apartment building reported gunshots fired from the building on Castaic Road, just north of Lake Hughes Road. “It was not shots fired at deputies,” Waterman said. “It was shots heard from that location.” “We are treating it as a barricade situation,” Waterman said, shortly after the initial report. “Right now, we are trying to make contact with the woman. We are also conducting evacuations at the building. “Nobody has been hurt. Deputies have not been hurt. Deputies did not return fire,” Waterman said. Subsequently, more deputies were dispatched to the scene, described as involving a barricaded suspect. Mental health officials were also dispatched to the scene.
