Police just released Amy Hillyard’s psychiatric evaluation, and it’s not what anyone expected. While the report is pages long, investigators are hyper-focused on the second line—handwritten in red ink. This single sentence is dismantling her husband’s alibi and turning the entire investigation upside down. What did she know that he tried to hide?

Husband reveals new timeline and health details

Chris Hillyard said Amy had been in treatment for depression and anxiety following the loss of a close friend and one of the family’s dogs, as well as caring for relatives. On March 25, they had breakfast together before he dropped her at a BART station for a therapy appointment in Walnut Creek. Later that day, she was recorded by surveillance near Dimond Park at 4:30 p.m., after returning home, walking their dog, and leaving her personal belongings inside with the back door open. San Francisco Chronicle + 2

Why these new details heighten concern

Police have said there is no sign of abduction or other crime, but Amy is considered at risk because of a medical condition. Her husband noted that missing her medication could be dangerous for her, and no note or explanation was left behind. The sequence of events showing her last seen on foot near hiking trails without essential belongings has guided search efforts toward those areas. San Francisco Chronicle + 2

Volunteers mobilize for East Bay canvassing

Family, friends, and community members have coordinated large-scale searches, canvassing neighborhoods, reviewing surveillance, and checking popular hiking spots like Skyline Gate and Reinhardt Redwood Regional Park. Volunteers use mapping tools to track covered areas and plan daily routes, while local businesses have donated food and printing services. Organizers say the community’s response reflects Amy’s longstanding contributions to local causes. SFGATE + 1

From therapy session to disappearance: the key moments

After her therapy appointment in Walnut Creek, Amy texted Chris to confirm she was home, took their dog for a walk, and spoke with a neighbor. By 3:15 p.m., Chris found her belongings inside and the back door open. Later that afternoon, surveillance placed her near Dimond Park, but searches there and in surrounding areas have not produced new leads. San Francisco Chronicle
