Pierre and Andrews then propped each of the victims into sitting positions and forced them to drink the liquid, telling them it was vodka laced with sleeping pills. Rather, it was liquid Drano, that immediately caused blisters on the victims' lips, and began burning their tongues and throats, and peeled away the flesh around their mouths. Ansley, still begging for her life, was forced to drink the drain cleaner too, although she was reported (by Orren Walker) to have coughed less than the other victims. Pierre and Andrews tried to duct tape the hostages' mouths shut to hold quantities of drain cleaner in and to silence their screams, but the oozing blisters prevented the adhesive from sticking. Orren Walker was the last to be given the drain cleaner, but seeing what was happening to the other hostages, he allowed it to pour out of his mouth and then mimicked the convulsions and screams of his son and fellow hostages.
