Seventeen-year-old Mary Hembree, also known as Oli, was last seen in Holden, Maine, on November 2, 2025. She was expected to spend the night with friends in nearby Brewer but did not return home; family and police report she has not been heard from since. Public missing-child listings describe her as white, with brown hair and blue eyes.

Mary’s cellphone reportedly last pinged in the Portland area before it was shut off, which expanded the search area well beyond Holden and Brewer. Her parents told police they believed she might have been traveling to Massachusetts to meet a boyfriend named Theo, whose last name has not been made public. The Holden Police Department has asked anyone with information to come forward and provided a contact number for tips.

This remains an active missing juvenile case centered on a narrow set of known facts. If anyone saw Mary after November 2, 2025, or has information about travel toward Portland or Massachusetts, please contact the Holden Police Department.
