Why this case is considered at-risk
The Los Angeles County Sheriff’s Department labeled Miller at-risk because she has diminished mental capacity and a health condition that requires medication. Missing persons who need regular medication or who have cognitive impairments face increased danger if separated from care or medication.
Family members have voiced growing concern for Miller’s well‑being and asked the public to check any possible sightings or information that could help locate her.
What investigators are asking from the public
Detectives ask anyone who saw Miller in La Puente after Feb. 10, 2026, or who may have seen a young woman matching her description traveling toward or from Southern California to Buffalo, N.Y., to contact the Missing Persons Detail. Residents along Harvestmoon Street and regular drivers on that route are encouraged to review doorbell cameras, home security systems, dashcams and surveillance footage from Feb. 10–14.
Law enforcement also asks neighbors, bus drivers and local businesses to report unusual activity observed in the days after Feb. 10.

Local context: La Puente and the Inland Empire
La Puente, on the western edge of the Inland Empire in eastern Los Angeles County, sees daily commuter traffic, transit lines and frequent movement by car, bus and train. Investigators stress that residents across the Inland Empire and Southern California remain alert for Miller or information that could lead to her location. Related regional coverage is available via the MyNewsLA crime category.
Public records and additional leads
As of the latest reports, there are no additional updates, photos or conflicting accounts beyond the initial alert issued by deputies on Feb. 15. Local news outlets have reiterated the sheriff’s department description and contact information but have not posted verified images of Miller. Detectives continue to pursue leads and encourage anyone with information to come forward.
Community safety tips for at-risk missing-person cases
- Check and save any home security or doorbell camera footage covering nearby streets between Feb. 10 and Feb. 15.
- Ask neighbors and local businesses whether they noticed a woman matching the description or an unfamiliar vehicle.
- Monitor transit stops and bus routes; post flyers in community hubs if safe and appropriate.
- If you see someone confused, disoriented or in need of medical attention, call 911 immediately and then notify the Missing Persons Detail.
- Avoid confronting strangers who may be in distress; contact authorities so trained personnel can assist.
Implications for the Inland Empire
Economic: While missing-person cases do not directly alter the local economy, they can strain resources when multiple agencies coordinate searches and community outreach requires volunteer time and modest spending on flyers and awareness campaigns.
Political: The case may prompt questions about community policing, mental‑health outreach, interagency coordination, and whether additional resources are needed for at‑risk missing-person responses.
Social & Cultural: Neighborhood groups, faith-based organizations and community centers may mobilize to support searches, share verified information, and check vulnerable residents using neighborhood apps and bulletin boards. Posting law-enforcement-approved details helps prevent rumors and focuses community efforts.
