Although Gacy remained gregarious and civic-minded, several neighbors noticed behavioral changes after his 1976 divorce, including seeing him keeping company with young males, hearing his car arrive or depart in the early morning, or seeing lights in his home switch on and off in the early hours. One neighbor later recollected that, for several years, muffled high-pitched screaming, shouting, and crying had repeatedly awakened her and her son in the early morning. She identified the sounds as emanating from a house adjacent to theirs on West Summerdale Avenue.
