Facing the death penalty, Delaney offered to make a deal: in return for leniency, he would give police the name of the real "career girls" killer, and he claimed it was not Whitmore . Delaney's wife, Marjorie, was also an addict and a prostitute . </P> <P> Delaney explained to police that on the day of the killings he had met an old acquaintance, Richard "Ricky" Robles, who had told him that he had committed the murders . Robles, a 22 - year - old burglar, had a long record of drug use and had been released from prison just two months prior to the murders . To support his habit, Robles needed anywhere from $30 to $50 per day . </P> <P> Delaney told detectives that Robles had turned up at his apartment on the day of the killings, his hands and clothes covered in blood, and demanding drugs . The shaken Robles told Delaney, "I just iced two dames ." His clothes had blood spatters on them; Delaney gave him a shirt and a pair of pants to change into . Delaney said he then went out to buy drugs with money Robles had given him . </P>
