Three-year-old William Tyrrell disappears in Kendall, New South Wales, Australia

William Tyrrell (born 26 June 2011) is an Australian boy who disappeared at the age of three from Kendall, New South Wales, on 12 September 2014. He had been playing at his foster grandmother's house with his sister, and was wearing a Spider-Man suit at the time of his disappearance. For the first seven years of the investigation, Tyrrell was believed to have been abducted. On 12 September 2016, a reward of A$1 million was offered for the recovery of Tyrrell and does not require the arrest, charging or conviction of any person or persons. On 15 November 2021, after receiving new evidence, NSW police renewed the search for Tyrrell in three areas surrounding Kendall, assuming that they were searching for human remains. On 17 November 2021, major media reported that Tyrrell's foster mother and now-deceased foster grandmother were being treated as persons of interest in his disappearance. The police began investigating the possibility of a fall from a balcony on the property.
