On the night of January 14, 1980, 30-year-old Theresa Gilligan, her husband Patrick, 30, and their children Lisa, 5, and Gregory, 4, were murdered in their Evansville, Indiana home after interrupting a burglary. The intruder, identified as Donald Ray Wallace, reportedly entered the house while burglarizing it. The family was bound with a vacuum cleaner cord and each was shot in the head.

Investigators tied Wallace to the scene through similar methods of entry to earlier burglaries, blood from the victims on his clothing, and stolen items from the Gilligan home found in his possession. He was arrested within days and later tried; in 1982 Wallace was convicted on four counts of first-degree murder and burglary and sentenced to death.

Does anyone have memories of the neighborhood or knew the Gilligan family that could add context to what happened that night?
