The Sonniers drove the couple to an oilfield in Iberia Parish and parked by the road. They handcuffed LeBlanc to a tree in a nearby wooded area. They took Bourque from the car and Elmo raped her. The brothers told her they would release both her and LeBlanc unharmed if she had sex with Eddie James Sonnier. Bourque agreed. Afterward, the brothers took the couple back to the car and removed their handcuffs. Elmo Sonnier decided against releasing them, as he feared the couple would report the incident and he would be reincarcerated at Angola. The brothers forced the couple to lie face down in a ditch and fatally shot them several times.
