Suspect in custody in shooting at detox treatment facility in Northern California that left 1 dead

Detectives have a suspect in custody and are interviewing the person about a shooting that killed one and injured two others at a detox facility in Marin County, officials said Monday.

Authorities identified the suspect as Davance Lamar Reed, a 37-year-old transient who was dating one of the victims, according to the Marin County Sheriff’s Office. Reed made statements to detectives that linked him to the crime scene.

Investigators determined that the shooting was an isolated incident and that the community was under no threat.

The Sheriff’s Office said authorities received a call at 1:33 a.m. from the Helen Vine Detox Center in San Rafael reporting that staff members had been shot.


Deputies arrived to find three people with gunshot wounds.

One man, whose identity has not been released, died at the scene. Another man and a woman — identified as facility employee Anthony Dominguez Mansapit, 32, and Brittney Kehaulani McCann, 30 — were taken to Marin General Hospital after the shooting and are in the intensive care unit, authorities said. Authorities said McCann was dating the suspect.

The Helen Vine Recovery Center, at 301 Smith Ranch Road in San Rafael, is a licensed 26-bed coed facility that offers both detox and residential substance use disorder treatment. Clients can stay up to 30 days for detox and up to 90 days for residential treatment. Last year, the staff at Helen Vine saw more than 900 patients.

The center is run by Buckelew Programs, the largest provider of community-based mental health and support services in the North Bay. The organization sees almost 10,000 people in Marin, Sonoma, Napa, Mendocino and Lake counties. It also runs the North Bay Suicide Prevention Hotline.

“While it is unimaginable to think that such a horrific event occurred at one of our facilities, it’s important to remember that Buckelew Programs has been providing safe and effective services for decades; improving the lives of tens of thousands of people,” Tamara Player, Buckelew’s chief executive, said in an email.
