Emmett Lynch, 57, and Mary Hooper, 62, were found murdered inside a residence on South Lyons Avenue in Tyler, Texas, on October 7, 1987. A visiting nurse who had come to provide care discovered both victims deceased at the home. Authorities reported no immediate signs pointing to a motive, and investigators were puzzled that neither the assailant nor a reason for the killings was apparent.

The case was thoroughly investigated at the time but ultimately went cold and remains unsolved. The Tyler Police Department continues to list the double homicide among its cold cases and has appealed to the public for tips, asking anyone with information to contact the department or Tyler-Smith County Crime Stoppers. Did anyone in Tyler at the time notice unusual activity around South Lyons Avenue on or before October 7, 1987?
