Robert Jerome "Bobby" Walker was a 16-year-old boy navigating a difficult life. Described as independent and somewhat street-smart, he had drifted away from his immediate family and was living on the fringes of Chicago society. By late 1976, he was moving between jobs and residences, a transient lifestyle that made him vulnerable. He was known to be trusting and willing to help others—a trait that serial predator John Wayne Gacy would exploit with ruthless efficiency.
It is believed that Gacy approached Walker with a familiar ruse: an offer of construction work, a request for assistance with a hypothetical "broken car," or an invitation to his home for drinks. Walker, likely seeking steady work or simply being hospitable, accepted the offer. He entered Gacy’s home at 8213 Summerdale Avenue, unaware that he would never leave.
