Among the three missing teenagers, family members have identified one as 14-year-old Emma Clark, who lives in Flagstaff. Clark's relatives have been actively searching since she left the facility with two other girls. Officials have released limited personal details to help the public recognize her and to aid in efforts to reunite the teens with their families and caregivers.

Emma Clark is described as standing 5 feet 6 inches tall and weighing approximately 130 pounds. She has brown hair and brown eyes. At the time she ran away, she was last seen wearing a black shirt and black leggings. Those physical details have been circulated by authorities and family members as part of the effort to locate her and the two other teenagers.

A family photograph released with the missing-person advisory shows Clark wearing a white top and carrying a backpack. The image has been shared publicly so that community members who may have seen the group can more easily identify her.

Authorities report the three girls were last seen running west into desert terrain in the vicinity of McDowell and Hawes Roads in Mesa. That area includes stretches of open desert and sparse development, and deputies working on the case have emphasized the importance of timely tips from anyone who may have been in the area or who may have observed the teenagers after they left the facility.

The Maricopa County Sheriff's Office has provided a contact number for members of the public who believe they have relevant information. Anyone with details that could assist in locating the missing teens is asked to call the sheriff's office at 602-876-1011. Law enforcement officials are handling the investigation and are coordinating with family members as the search continues.

As of the release of the advisory, Emma Clark has been publicly identified by her family, while the two other girls who left the facility with her have not been named in the information shared by authorities and relatives. The focus of the public notice is to gather any leads that could help locate all three teens and to ensure they are returned to care safely.

The sheriff's office statement and the family's outreach reflect ongoing efforts to locate the missing teenagers and to obtain information from the public. Anyone with information about where Emma Clark or the two other girls might be is urged to contact the Maricopa County Sheriff's Office at 602-876-1011 so investigators can follow up on tips and work to resolve the situation.

The Missing In America Network has amplified the search with a dedicated campaign for Emma Clark, who went missing on July 10, 2026, alongside two other juveniles. The nonprofit shared her details widely and provided an additional anonymous tip line at 1-844-MIA-LOST to supplement the Maricopa County Sheriff's Office number.
