One of the suspects in the disappearance of teenage cousins 50 years ago is still living in WA, a new documentary about the 1974 crime has revealed. The now elderly man breaks a 50-year silence to protest his innocence in the latest episode of Vanishing Cousins: Evil by the Beach. The crime series, produced by The West Australian, reveals new leads in the case of Raelene Eaton and Yvonne Waters, who vanished from Scarborough on April 7, 1974. Raelene, 16, and Yvonne, 17, were never seen again after leaving a Sunday session at the White Sands hotel. One of the first suspects, and a man police say remains a person of interest, was a 20-year-old who police believed had a crush on Raelene. Det-Sen. Const. Peter Shanahan, who led a cold case review of what happened in Scarborough half a century ago, says Raelene’s mother, Jean, headed to the man’s house after she visited a police station to speak about her missing child. “A lady who actually is the owner of the house states that the male friend is still in bed,” Det-Sen. Const. Shanahan says. “He got home late and he was up during the night using the washing machine.” The late-night use of the washing machine “requires further investigation”, according to Det-Sen. Const. Shanahan. The suspect told police in his original interview that on the day the girls went missing he had been searching for them but had failed to find them. “We’ve had a good look at everything concerning this particular person, and we cannot eliminate him as a suspect,” Det-Sen. Const. Shanahan says. “He remains a suspect to this day.” Producers from Vanishing Cousins tracked the man, who agreed to talk about his involvement in the case and protested his innocence. “That I am implicated disgusts me,” he says. “I first met Raelene Eaton at the Midland hotel. She looked like she was alone. I was alone. I offered her a lift home, and I took her home. That’s it. “One time, she invited me to Wedge Island. I drove her in my car. Her parents went in the other car. Mr Eaton and myself went fishing. They were hospitable. WATCH EPISODE 1: THE VANISHING “Raelene was just a presence. She wasn’t anything else. The day we went to Wedge Island was the only time we hugged. There was never anything beyond a hug that would solidify a relationship.” The suspect recalls the day the cousins went missing. “On the Sunday, I drove with a friend to Irvine Street, Bayswater,” he recalls. “Raelene was not home. Apparently she had gone to the White Sands, her father said. I drove my friend to his address in Scarborough and dropped him off. WATCH EPISODE 2: THE SUSPECTS “I’m going to see Raelene, but I don’t have any money. I was down to my last cent. So I went back to my lodging house.” Episode three of Vanishing Cousins: Evil by the Beach also tells the heartbreaking death of Raelene’s brother Graham, who was killed in a car crash while searching for the cousins.
