In total 16 people were murdered by Burke and Hare.[81] Burke stated later that he and Hare were "generally in a state of intoxication" when the murders were carried out, and that he "could not sleep at night without a bottle of whisky by his bedside, and a twopenny candle to burn all night beside him; when he awoke he would take a drink from the bottle—sometimes half a bottle at a draught—and that would make him sleep."[82] He also took opium to ease his conscience.[83]
