On 12 September 2014, 3 year old William Tyrrell was playing in the front yard of his grandmother's home at Kendall, a small country town on the NSW mid-north coast, when he suddenly disappeared.
And two years on, police still have no idea what happened to him.
This week, police announced a $1 million reward for any information concerning his disappearance, the largest reward ever offered in the state's history.

Inspector Gary Jubelin said "If you've got information regarding William's disappearance and you've got concerns that you could be potentially complicit in the offence, by concealing the offence, that offence will be negated the moment you come to police."
He said anyone who comes forward will have their identity protected and he would personally guarantee the safety of any informants.
"I'm confident it's only a matter of time before we find out what happened to William and if we come to you - the reward is off the table" he said
So the disgusting workings of the paedophile's mind has parents everywhere terrified to leave their little child unattended while playing alone in their own front yard.
And police say they have 690 deviant scumbag persons of interest, so what hope have parents got?
