When the boys finally arrive that night, they find Lux alone in the living room, smoking a cigarette. Thinking they're going to help the girls escape, the boys are invited inside by Lux to wait for her sisters, while she goes to start the car. Curious, the boys wander into the basement after hearing a noise and discover Bonnie's body hanging from the ceiling rafters. Horrified, the boys rush back upstairs, only to stumble across the body of Mary in the kitchen. The boys then realize that the girls had all killed themselves in an apparent suicide pact moments earlier: Bonnie hanged herself; Mary put her head in the gas oven; Therese overdosed on sleeping pills; and Lux died of carbon monoxide poisoning by leaving the car engine running in the garage.
