Seventeen-year-old Mary Hembree, also known as Oli, was last seen in Holden, Maine, on November 2, 2025. Public missing-child listings identify her as a 17-year-old female missing from Holden, and the National Center for Missing & Exploited Children lists her missing date as November 2, 2025, with an instruction for anyone who sees her or has information to contact authorities.
Other missing-child alerts describe Mary as white, with brown hair and blue eyes, and continue to associate her case with Holden, Maine. The available public information presents the beginning of the case as a sudden and frightening break in routine: Mary was expected to be spending the night with friends in Brewer, a nearby community, but she did not return home as expected.
After Mary did not come home, the Holden Police Department began asking for the public’s help. Local reporting stated that police described her as a missing juvenile and said she had not been heard from since November 2. The concern deepened because her cellphone reportedly last pinged in the Portland area before it was shut off, moving the focus of worry well beyond Holden and Brewer and raising questions about where she may have gone after leaving the area. Police and local media also reported that Mary’s parents believed she might have been traveling to Massachusetts to meet a boyfriend named Theo, though his last name was not known publicly in the reports.
The public appeals emphasized the urgency of locating Mary safely and gathering even small pieces of information that might help investigators. Newport Dispatch reported that anyone with information on Mary’s location was asked to contact the Holden Police Department at 207-843-5442, while another local report listed Holden police as the point of contact as the search continued. Missing-child listings also urged people with possible information to come forward, stressing that details that may seem minor could still matter in a missing child case. In the information available from public online sources, the case is centered on a teenager from Holden who was expected to be with friends in Brewer, did not return home, had a phone last associated with the Portland area before it went silent, and may have been headed toward Massachusetts; overall, Mary Hembree’s case remains a deeply concerning missing juvenile case built around a narrow set of known facts and a continuing need for anyone with credible information to contact law enforcement.Last Seen: Nov 2, 2025
