Pierre then ordered Andrews to go out to their van and bring him back something. Andrews returned with a bottle in a brown paper bag, from which Pierre poured a cup of blue liquid. Pierre ordered Orren to administer the liquid to the other hostages, but he refused, and was bound, gagged and left face-down on the basement floor.
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. The moment it touched the hostages' lips, enormous blisters rose, and it began to burn their tongues and throats and peel away the flesh around their mouths. Ansley, still begging for her life, was forced to drink the drain cleaner too, although she was reported to have coughed less than the other victims (by Mr. Walker). Pierre and Andrews tried to duct-tape the hostages' mouths shut to hold quantities of drain cleaner in and to silence their screams, but pus oozing from the 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 faked the convulsions and screams of his son and fellow hostages.
Pierre became angry because the deaths were taking too long and were too loud and messy, so he shot both Carol and Cortney Naisbitt in the backs of their heads. Pierre then shot at Orren Walker but missed. He then fatally shot Stan Walker before again shooting at Orren, this time grazing the back of his head.
