One small, 96-minute window could provide the breakthrough police need to finally solve the mystery of what happened to William Tyrrell.

A critical 96-minute window between when William Tyrrell’s foster dad drove to the shops and police arrived at the scene the day the three-year-old disappeared could hold the key to solving the baffling case. Mobile phone records have shown that William’s foster father left his mother-in-law’s home in Kendall at 9.30am on Friday, September 12, 2014.
He was photographed in his Spider-Man suit at 9.37am that day, with the snap becoming the defining image of the heartbreaking mystery. Police believe William disappeared between 10.05am and 10.20am, and police arrived at the home at 11.06am, kicking off the investigation. Attention is once again turning to that tight timeline, after a number of key details in the William Tyrrell investigation emerged overnight, after police revealed the boy’s foster parents had been charged with the alleged assault of a child — not William — on Sydney’s upper north shore.
In the latest development, police are reportedly focusing on a key detail in the widely known image of three-year-old Tyrrell wearing a Spider-Man suit. The photo was taken on the day the little boy disappeared and according to The Daily Telegraph, police are looking into detail surrounding witness statements from William’s foster mother, who claimed he was wearing shoes on the day he disappeared to protect his feet from bindis and dog poo.
In the image, taken less than an hour before he went missing, William is barefoot. It is one of a number of inconsistencies in the statements from that fateful day that has seen detectives return to the home in Kendall where William was last seen. The masthead reported police are also investigating the idea there were no bindis or dog poo on the lawn. Earlier, detectives, who had been searching the Kendall home of William’s foster grandmother for the boy’s body were said to be focusing their investigation on the child’s foster mother.
According to The Daily Telegraph, the 56-year-old woman, who had been caring for William since March 2012, is now the key police suspect. She has not been arrested or charged over William’s disappearance.
