Teen Vanishes While Searching For Bigfoot
Theresa Ann Bier was lured to the mountains by a known predator who was obsessed with Bigfoot.
Theresa Ann Bier had a rough upbringing. Her parents, Shirley and David Bier, did not provide a safe and loving home for Theresa and her siblings in Fresno, California. Shirley was particularly abusive towards her children. On one occasion, Theresa had to be taken to a hospital due to an injury sustained at home — Shirley had wrapped 3-year-old Theresa’s leg around one of her crib’s slats and twisted it until it broke.
As a result of their unstable home environment, social services removed Theresa and her siblings from their parents’ care and put them in foster homes.
A few years after Theresa had been placed in the care of a family friend, her father decided that he wanted her custody back. David had divorced Shirley and remarried Margie Richmond. Margie had previously been married to Shirley’s half-brother, John Richmond, and they had two daughters who lived with her and David. The father was granted custody and they moved to Southern California. During this time, Margie was reportedly abusive towards her daughters and Theresa.
Theresa would eventually return to Fresno to her great-grandmother’s house. Although David tried to get her back to Southern California, she refused and he soon lost interest.
