Mary Ann Humfreville, 74, vanished from her home in Bahía de los Ángeles, Baja California, with last confirmed contacts on December 16, 2020. That afternoon she spoke by phone with a son around 3:30 p.m. and messaged a friend near 4:00 p.m.; those were her final known communications. She missed a breakfast appointment the next morning, December 17, and friends who checked her house found her dog and cat inside and many personal items undisturbed.

Her red 1998 Ford F-150 with California plates (7A92402) was gone, along with a generator and a small Honda outboard motor. Her purse containing ID, bank cards, and cash was left in the house, but a cat box where she reportedly hid cash was empty. The door she usually used was locked from the inside, and friends think intruders may have entered through a side door. Mary Ann had lived in Bahía de los Ángeles since the early 1970s after moving there with her late husband Mike Humfreville; she continued to live there despite limited resources and land ownership issues.

No whereabouts have been established since December 17, 2020. Did anyone in Bahía de los Ángeles see Mary Ann’s pickup or notice anything unusual around December 16–17, 2020?
