- Missing: Alyssa Isabella Miller, 20, last seen Feb. 10 near the 16100 block of Harvestmoon Street in La Puente.
- At‑risk: Miller has diminished mental capacity and a medical condition that requires daily medication.
- How to help: Contact the Los Angeles County Sheriff’s Department Missing Persons Detail at (323) 890-5500 or submit anonymous tips to Crime Stoppers.
Details of the disappearance
Alyssa Isabella Miller was reported missing after family members raised concerns for her well‑being. According to the Los Angeles County Sheriff’s Department, Miller was last seen on Tuesday, Feb. 10, 2026, in the area of the 16100 block of Harvestmoon Street in La Puente. Family members said she last spoke with them on Feb. 14 at about 12:08 p.m.
Description: White female, approximately 5’4″, ~180 lbs., brown hair, brown eyes. Clothing when last seen: white T‑shirt and blue jeans. Investigators say she may be traveling toward Buffalo, New York, though that has not been confirmed.
Which agency is handling the case
Official records and the missing persons alert identify the Los Angeles County Sheriff’s Department (LASD) Missing Persons Detail as the agency coordinating the search. Social posts that referenced the LAPD were inaccurate; the LASD Missing Persons Detail is the central contact for tips and updates.
Why investigators are concerned
Investigators and family members emphasize two main concerns: Miller’s need for daily medication and her diminished mental capacity. The LASD alert classifies her as an at‑risk missing person because those vulnerabilities increase the danger of rapid health decline if she has missed medication.
“Timely information is crucial,” authorities said, noting that even small details can be critical to locating at‑risk missing persons.
Public appeal and how to help
The LASD Missing Persons Detail asks anyone who saw Miller or has information about travel plans or possible sightings to call (323) 890-5500. Anonymous tips may be submitted to Crime Stoppers at (800) 222-TIPS (8477), via the P3 Tips app, or through the Crime Stoppers website.
Investigators say even seemingly minor leads — a sighting, vehicle description, license plate, social post, or travel receipt — could help narrow the search.
Journalistic checks and gaps in reporting
Reporting so far is based on the initial alert published Feb. 15, 2026. No public photographs accompanied the LASD notice, and there have been no confirmed sightings or updates since the alert. The timeline shows a gap between the last confirmed sighting (Feb. 10) and her last contact with family (Feb. 14); authorities have not released details of Miller’s movements during that period.
The original alert and subsequent reports were issued by the LASD and by Times Media Service reporting via MyNewsLA.
Potential travel and investigative next steps
If investigators pursue the possible Buffalo destination, they will likely review transit records, camera footage at bus and train stations, airline records, and digital traces such as phone pings or social media activity. Authorities may coordinate with transit agencies, Greyhound, Amtrak and airports to trace movements.
What families and neighbors can watch for
Check shopping centers, parks, transit stations, motels, and homes of friends. Hospitals and clinics may encounter someone who needs medication; investigators routinely query medical facilities. Note time, location and any vehicle or accompanying persons, then contact the LASD Missing Persons Detail.
Privacy and safety considerations
Residents should avoid sharing unverified rumors on social media to prevent wasted resources and additional distress for the family. Those who believe they have direct contact with Miller should call law enforcement immediately instead of approaching her, and anonymous reporting options are available via Crime Stoppers.
Implications for Las Vegas, Nevada
Community awareness: Las Vegas is a major transit hub; staff at bus terminals, Amtrak, airports and hotels should be vigilant for a young adult matching Miller’s description and report sightings to local law enforcement and Crime Stoppers.
Health and social services: Emergency rooms, urgent care centers and community clinics can help by checking for unregistered patients who match Miller’s description and notifying authorities.
Contact information and sources
Anyone with information is urged to call the Los Angeles County Sheriff’s Department, Missing Persons Detail, at (323) 890-5500. Anonymous tips may be submitted to Crime Stoppers at (800) 222-TIPS (8477), via the P3 Tips mobile app, or online at the Crime Stoppers website.
