In newly released police records about the shooting deaths at the Veterans' Home in Yountville last year, experts see several red flags.
The Napa County Sheriff's Office records show that before Albert Wong, a former Army infantryman and client of the Pathway Home program, killed three employees and himself, he talked about shooting the staff several times.
Psychotherapist and consultant to therapists Renee Lonner said these were warning signs, although generally her profession involves little training in assessing threats.
"When I'm a consultant for therapists who have been threatened by a former or current patient, they call me -- not clueless, I wouldn't say that, but terrified and without prior training," Lonner says. "And these are people out of the best universities, the best graduate schools."
The San Francisco Chronicle reported first about the police records.
Michele Licht is an attorney who represents mental health care providers. She and Lonner advocate for better training.
"How do we train people on the red flags so they can see warnings?" Licht said. "And then how do we help them report it? Because in too many cases, including the one in Yountville, there were signs."
Christine Loeber, Jennifer Golick and Jennifer Gonzales were killed in the March 9, 2018 shooting. Months after the attack, the Pathway Home program closed permanently due to logistical and emotional difficulties.
