Mary Goss, 39, of Garland, Texas, was murdered on November 15, 1989. The man identified in connection with her killing was Daniel Joe Hittle, who had an earlier history of violence and was on parole at the time. On the night in question Hittle attended a party at Goss’s home, left, went to his own house and argued with his wife, then drove back armed with a 20-gauge shotgun.

Garland police officer Gerald Walker stopped Hittle for speeding; Hittle shot him in the chest, then went to Goss’s house and killed Mary Goss along with her boyfriend Richard Cook Jr., 36, her friend Raymond Gregg, 19, and Goss’s 4-year-old daughter Christy Condon. Hittle was arrested after a chase and a gunfight with police and was later convicted in the case of Officer Walker and sentenced to death.

Does anyone have additional details about Mary Goss, her life in Garland, or witnesses from that night who might fill in unanswered questions?
