Dallas Police Seek Help Finding Endangered Missing 13-Year-Old After Late Night Disappearance in Lake Highlands Last Week
DALLAS, TX — Dallas police are asking the public to help locate a 13-year-old girl who was reported missing in the Lake Highlands area and has been classified as endangered. Investigators say Natalie Armstrong may be in need of assistance, and they released an updated notice as they continue to search for her.
Police said Armstrong was last seen walking on foot late Wednesday night in northeast Dallas. Authorities have not said where she may have gone after that sighting, but they are treating the case with urgency and urging anyone with information to come forward quickly.
Last known sighting in northeast Dallas
According to Dallas police, Armstrong was last seen at 10:08 p.m. on Oct. 21, 2026, in the 9300 block of Whistle Stop Place. That location is in the Lake Highlands area of Dallas, a neighborhood in the city’s northeast side.
Police said she was on foot when she was last observed. No additional details have been released about the circumstances of her disappearance or whether investigators believe she left the area alone or with someone else.
The updated alert does not say how long she had been missing before the endangered missing person designation was issued, but it makes clear that police want the public to treat the case seriously.
Description released by investigators
Dallas police described Armstrong as 5 feet 3 inches tall and about 135 pounds. She has brown hair and hazel eyes, according to the department’s description.
She was last seen wearing a gray hoodie, blue jeans and white shoes. That clothing description is one of the main details investigators are using as they ask for tips from people who may have seen her in the area or later that night.
Officials have not released any further identifying details beyond her physical description and clothing. They have also not said whether they have recovered any belongings or received possible sightings since the original report.
Why police labeled the case endangered
By calling Armstrong an endangered missing person, Dallas police are signaling that they believe she may be vulnerable and could require help from others. The department did not provide a more detailed explanation for that designation, but the label is used when authorities want to increase awareness and encourage rapid public assistance.
Such alerts often prompt broader attention from residents, especially when a missing child is last seen walking at night. In this case, police have framed the search as a critical update and are continuing to seek information from the community.
Investigators have not released any indication that foul play has been confirmed, and they have not publicly identified any person of interest.
How the public can share information
Anyone with information about Armstrong’s whereabouts is being asked to call 911 right away or contact the Dallas Police Department at 214-671-4268. Police want callers to reference case number 155505-2026.
Authorities are urging people to report even small details, including possible sightings in the Lake Highlands area or elsewhere in Dallas. In missing person cases, tips from neighbors, drivers, store employees and other witnesses can sometimes help investigators narrow down a timeline.
Police have not announced a specific search area or asked residents to shelter in place, but they are clearly treating the case as active and continuing to gather leads.
What remains unknown as the search continues
Police have not said where Armstrong may have gone after she was last seen, and they have not shared any update on a possible destination, companion or travel method. The department also has not released information about whether her family has heard from her since Wednesday night.
For now, the most recent official information remains the description and location tied to the Oct. 21 sighting. Until investigators get a confirmed lead, the search depends heavily on the public noticing something useful and reporting it quickly.
Dallas police say the case remains open, and the department’s alert is aimed at generating fresh tips that could help bring the teenager home safely.
