Christina Lynn Bastian, 34, was last seen in the early hours of November 1, 2015, in Apple Valley, California. She had been staying at a friend’s house after a church event the night before and reportedly left abruptly around 1:45 a.m., taking her small dog, Coco, while leaving behind her wallet, glasses, and identification.

That same day Christina’s belongings were found scattered along Highway 247, and her truck was later located abandoned in Morongo Valley with visible damage. In the days before she vanished she showed increasingly erratic behavior after stopping her medication for bipolar disorder, and she expressed fears of a break-in and talk of making major life changes. Her dog Coco was recovered but Christina has never been found.

No evidence of foul play has been reported, though her mental health and the strange sequence of events are major concerns. Anyone with information about Christina’s whereabouts is asked to contact the San Bernardino County Sheriff’s Department.
