SAN FRANCISCO—The San Francisco Police Department took into custody a suspect who engaged authorities in a near 24-hour standoff on Monday, July 11. According to a press release from the SFPD, at approximately 6:00 p.m. officers responded to a home on the 500 block of Campbell Avenue to check on the welfare of a person who made several calls to 911.

Dispatchers from the Department of Emergency Management were not able to determine the nature of the emergency and had officers dispatched to attempt to contact with the caller. After arriving on the scene, officers from the Ingleside Police Station contacted the occupant and determined the individual was in crisis and threatening to commit suicide. Authorities conversed with the subject and asked for help from the Department’s Crisis Hostage Negotiation Team. While speaking to officers, the subject made threats to blow up the home, which prompted authorities to evacuate neighboring homes in the region.

The San Francisco Fire Department were called to the scene and gas service to the home was turned off. Crashing noises from the inside of the home, where the suspect covered multiple windows, one was blocked with a mattress. The stand-off lasted nearly 22 hours. During the afternoon hours on Tuesday, the subject became agitated and started making suicidal threats again, where he stepped through the living room window and onto a ledge, threatening to jump. He threw liquid bleach on the front gate and onto several officers who were part of the arrest team.

Several of the officers were treated for exposure to the bleach, including one officer whose eyes were exposed to the chemical.

Police took Magnom F. Carolino, 51, of San Francisco into custody at approximately 3:43 p.m., when it was evident he was drinking bleach. He was taken to a local hospital for treatment and booked at the San Francisco County Jail for 12 counts of assault with a caustic chemical, 12 counts of aggravated assault on a peace officer and making a false report of a bomb and resisting arrest.

No officers suffered life-threatening injuries. The SFPD Explosive Ordinance Disposal Unit searched the home and did not find any destructive devices.

Monday’s incident involved several Crisis Intervention Team trained officers who worked to create time and distance and establish a rapport with the subject. The resolution of this standoff reflects the Department’s ongoing commitment to de-escalation tactics designed to bring such critical incidents to a peaceful conclusion, whenever possible.
