Richard Joseph Cook Jr., 36, was killed on November 15, 1989, in Garland, Texas, during a violent spree carried out by Daniel Joe Hittle. Hittle, who was on parole at the time and had previously served 11 years for the 1973 stabbing deaths of his parents in Minnesota, began the rampage after a traffic stop in which he shot Garland police officer Gerald Walker in the chest with a .20 gauge shotgun.

After that shooting Hittle drove to Dallas and continued killing. Among the victims were Mary Goss, 39, her daughter Christy Condon, 4, Richard Joseph Cook Jr., who was Goss’s boyfriend, and Raymond Scott Gregg, 19. Hittle was arrested after a car chase and gunfight and was charged with multiple counts of murder; only the killing of Officer Walker was tried. Families affected by the spree were left to reckon with the losses and the fact Hittle had been on parole when the killings occurred.
