On the morning William disappeared, Mr Spedding was supposed to be at the house to carry out repairs, but he was unable to contact William’s grandmother by phone, Mr Youngberry says.
Instead, at that “crucial time” when William went missing, the Speddings were sitting at the Buzz Cafe in Laurieton, 10km from Kendall, according to Mr Youngberry.
“They have got proof that they were at the cafe because he paid for the coffees by card,” he said.

Man ‘at cafe’ when William disappeared
Mr Spedding, 63, told of a conversation he had with William’s grandmother at her home when he inspected the machine.
Mr Spedding has claimed to relatives and police he was never due to visit Kendall on the day three-year-old William vanished, September 12, 2014, and was simply calling to say the part needed to repair the washing machine had arrived.
