Theresa Fischbach, 17, disappeared after moving from St. Charles, Missouri, to Spring, Texas, with her boyfriend earlier in 1986. She was last heard from on May 24, 1986; the last direct contact with her family was a Mother’s Day card sent in May. No further communications or confirmed sightings have been reported.

At the time she went missing Theresa was described as 5 feet 3 inches, about 120 pounds, with brown hair and brown eyes. A distinctive tattoo of a cross between her thumb and index finger was noted as an identifying feature. The St. Charles Police Department investigated but very few details have emerged and the case remains unsolved.

If anyone knew Theresa, saw her after May 24, 1986, or recognizes the tattoo or other identifying details, please share what you know.
