Mary Hooper, 62, was murdered in Tyler, Texas, on October 7, 1987. She was found dead in her residence alongside 57-year-old Emmett Lynch. No arrests have been made and the Tyler Police Department treats the case as a cold case.

Investigators re-examined archives and retained material evidence over the years but have not produced conclusive results. The department notes that new technical methods developed since 1987 could potentially be applied to surviving evidence, and they have appealed to the public for witness testimony or DNA leads that might generate a breakthrough.

Anyone with information about the killings of Mary Hooper and Emmett Lynch is asked to contact the Tyler Police Department or Tyler Smith County Crime Stoppers.
