He remembered, for example, one night in 1975 when he encountered Gacy alone at 3AM, near the W. Miami property. At the time, Gacy was casually holding a spade — a shovel for digging, not moving snow — in his hand. Without being prompted, Gacy told him, laughing: “Bill, you know me, not enough hours in the day. You get it done when you can.” Only later did Dorsch think to ask a potentially disturbing question: Get what done?
