Tackett then asked the citizen if he would be willing to walk with him into several public places. Tackett had the idea that the suspect would not want to see the citizen and would try to avoid him. On a Saturday in July, Tackett walked into the Arkansas Motor Coach bus station on Front Street, near Union Station, with the citizen. Tackett saw a man run out the back of the building. Tackett chased after him and caught him on the fire escape. The man was Youell Swinney. Soon after arrest, he reportedly made what might have been incriminating statements about being a murderer, such as a fear of being sentenced to the electric chair. When police questioned Swinney's wife Peggy, she confessed in great detail that he was the Phantom Killer and that he had killed Betty Jo Booker and Paul Martin. Her story changed in some details across several confessions and conversations, and police believed she was withholding some facts due to fear of Swinney or fear of incriminating herself.
