Special Investigation: Where is William? One year ago a little boy vanished while he was playing in his grandmother’s backyard. One moment William Tyrrell, dressed in his favourite Spiderman suit, was playing games with his mum and sister, the next he was gone – as if he’d disappeared into thin air. Initial panic by his family slowly turned into the darkest of despair and a whole year later they are simply heartbroken. Who would take their vivacious, funny, innocent three-year-old boy? It’s a question that torments one of Australia’s toughest and most experienced detectives, who is heading the taskforce into William’s disappearance, and this Sunday 60 Minutes has unprecedented access to that investigation. For the first time William’s parents speak openly to reporter Michael Usher about their boy, in the hope that someone may have the courage to reveal information that will bring William home. Reporter: Michael Usher Producers: Laura Sparkes, Grace Tobin Women of Hart Jessica and Ashley Hart are the homegrown sisters who are our hottest catwalk exports. These days they call New York and Los Angeles home. It’s a long way from growing up with their single mum, Rae, in the suburbs of Melbourne. Their story is more than your typical rags-to-riches tale. The girls owe their success to their mother and the incredible sacrifice she made so they would always have each other. Reporter: Karl Stefanovic Producer: Steven Burling
