An Endangered Missing Advisory covering Los Angeles and Ventura counties was issued for a person last seen near Reseda Boulevard and Strathern Street in Reseda.
The alert was posted Wednesday, Oct. 21, 2026, at 3 p.m. by CHP - Alerts.
The advisory lists Reseda Boulevard and Strathern Street in Reseda as the last-seen location and asks anyone who sees the person to call 9-1-1.
The California Highway Patrol posted the advisory and tagged the Los Angeles Police Department. Reseda Boulevard and Strathern Street intersect in Reseda.
How the Alert System Works
An Endangered Missing Advisory is distinct from an AMBER Alert.
An EMA has its own activation criteria: the missing person must be at risk because of a qualifying condition, such as cognitive impairment, abduction or inability to care for themselves; investigators must have used available local resources, find the disappearance unexplained or suspicious, determine the person may be in peril and have information the public could use to help. Those criteria are outlined in the CHP’s Endangered Missing Advisory guidance; the advisory alone does not establish which circumstances apply in this case.
Requests like this one are evaluated by the Emergency Notification and Tactical Alert Center, a unit staffed around the clock at California Highway Patrol headquarters in Sacramento that coordinates activations across municipal, county, and tribal jurisdictions statewide, the agency's description notes. The Endangered Missing Advisory is one of six specialized alert types the CHP operates, alongside AMBER, Blue, Silver, Feather, and Ebony alerts. Once approved, CHP pushes the information out through freeway Changeable Message Signs, social media accounts, and Wireless Emergency Alerts when criteria are met.
The process is set in California law: AB 946 established Government Code Section 8594.11, allowing an investigating law enforcement agency to request an EMA and CHP to activate one if it agrees the criteria are met. The law provides for activation within an appropriate geographic area, rather than requiring every advisory to cover the entire state. Gov. Gavin Newsom signed AB 946 in 2023.
West Valley Division Listed as Tip Contact
The West Valley Division is listed as a contact for tips. LAPD guidance includes filing missing-person reports at local stations or by phone and collecting physical descriptions.
Beyond the immediate search area, no further detail has been released about what prompted investigators to classify the person as endangered. It's also unclear whether the search has expanded beyond the initial area near the Reseda intersection.
Other Recent Advisories
LAPD and CHP issued an advisory in Reseda on September 30 after four children vanished near a gray vehicle. Days later, a Reseda teenager with autism went missing from school. An advisory for 10-year-old Ian Moreno was in effect elsewhere in Los Angeles.
A September advisory from LAPD and CHP also centered on Reseda, but involved four children ages 1 to 9 last seen with their mother. The alert covered five Southern California counties, and authorities said the group might be traveling in a gray Toyota Prius. That case shows how an advisory tied to a Reseda disappearance can include a vehicle description and extend well beyond the neighborhood; the September 30 search was a separate case.
Anyone who sees the missing person is asked to call 9-1-1 immediately.
