Theresa Ann Bier, of Fresno has not been seen since she and Russell "Skip" Welch, 43, reportedly became separated in the mountains after they had gone to look for Sasquatch, the legendary creature also known as Bigfoot. Welch was charged with abducting Theresa but the charge was later dismissed.
Welch, a self-proclaimed student of Bigfoot, went camping with the girl in June near Shuteye Peak, about 25 miles northeast of Bass Lake, and was questioned by deputies when he returned without her. Welch's explanation was that Bigfoot had abducted her. Foul play is suspected. Searches throughout that region produced no sign of Bier; she has never been seen again.
