Alberto Rangel, UCSF Social Worker, Fatally Stabbed by Patient at San Francisco Hospital

SAN FRANCISCO, Calif. – The San Francisco community is mourning the loss of Alberto Rangel, a 51-year-old social worker at Zuckerberg San Francisco General Hospital, who died Saturday, two days after being stabbed by a patient. The attack has sparked outrage and renewed concerns about hospital safety.

Rangel, remembered by colleagues as a deeply caring and devoted professional, was attacked in the hospital’s HIV ward Thursday afternoon by a patient armed with a 5-inch kitchen knife. Witnesses say he was stabbed multiple times in the neck and shoulder. Despite lifesaving efforts, including CPR and emergency surgery, Rangel succumbed to his injuries on Saturday.

Hospital staff and union representatives have described the tragedy as “predictable and preventable.” Union members say they had long raised safety concerns about patients and security procedures, including requests for deputy protection in high-risk wards. According to witnesses, a deputy was present nearby when the attack occurred.

“For him to lose his life at work, when he was there to provide services to patients, it’s just not right. It’s a betrayal,” said Maddy Auble, a colleague who worked closely with Rangel in the HIV ward. Fellow social worker Julette Suarez added, “Alberto was one of the most beautiful people I’ve ever met. Amazing clinician. Unbelievable loss for staff and community.”

Authorities confirmed the suspect is in sheriff’s custody. Reports indicate the patient had previously sought out another doctor at a different clinic before arriving at Zuckerberg General Hospital. The incident occurred in a ward without metal detectors, intensifying concerns about safety and security.

Union leaders are calling for a thorough review and reforms. Dan Russell, president of University Professional and Technical Employees (UPTE), stated, “We are demanding a thorough investigation into what allowed this to happen and what changes need to be made, so this never happens again.” Chey Dean, UPTE co-chair, emphasized, “Our colleague and our friend and our loved one deserves more than our grief. They deserve change.”

The San Francisco Department of Public Health said it is working with the hospital to strengthen security measures, including adding more security personnel, limiting access points, and expediting weapons detection systems. Meanwhile, the San Francisco Deputy Sheriffs’ Association criticized recent cuts to deputy positions at the hospital, saying data showed serious assaults and weapons on campus were already a known risk.

Loved ones gathered at a candlelit vigil to honor Rangel's memory on Sunday 

Community members, including nurses, social workers, and medical students, gathered Sunday evening outside the hospital to honor Rangel. Candles and heartfelt tributes highlighted his dedication to patients. Carly Jones, a UCSF medical student, said, “I just pray for protection for everyone, peace, rest and healing. I want people needing care to feel safe, and those serving to be able to do their jobs safely.”

Rangel is remembered for his devotion to patients and enthusiasm for his work. “Alberto had so much more life to live. He was devoted to his patients. He loved his job. He was enthusiastic about what he did,” Auble said.

The Department of Public Health confirmed it is conducting a full investigation into the incident.
