In Today's episode, I dive into the mysterious 1987 disappearance of 16-year-old Theresa Bier in the remote Sierra Nevada mountains near Fresno, California. Accompanied by 43-year-old Russell Welch, a self-proclaimed Bigfoot hunter, Theresa vanished without a trace during an expedition in the wilderness. Welch was later arrested but never charged due to lack of evidence. What happened deep in those woods? Join me as I explore the strange circumstances, disturbing theories, and unanswered questions surrounding the Theresa Bier case—a mystery that still baffles investigators today.
