Summary based on the NamUs case record (MP13437) and 5 other sources
Theresa Fischbach, a 17-year-old from St. Charles, Missouri, went missing on May 24, 1986, shortly after moving to Spring, Texas, with her boyfriend earlier that year. Theresa had last contacted her family in May, sending her mother a Mother's Day card, which would be their last communication with her. Since then, she has not been heard from, and her current whereabouts remain unknown.

At the time of her disappearance, Theresa was described as having brown hair and brown eyes, standing 5'3" tall and weighing around 120 pounds. Notably, she had a tattoo of a cross between her thumb and index finger, which could help identify her. Despite efforts from law enforcement, including the involvement of the St. Charles Police Department, little information has surfaced in the decades since she vanished. Her case remains unsolved, and her family continues to search for answers.

Theresa's case is particularly haunting because there are very few details available, and no clear leads have been established. Investigators and organizations like NamUs and the Doe Network continue to hold out hope that more information will emerge to help solve this decades-old mystery.
