As a little boy plays in the yard, neither he nor his family sitting nearby know that their lives are all about to change forever.

The hours that followed William's disappearance were filled with confusion, mayhem and fear.

The names of people in this podcast have been changed for legal reasons. William's foster mother (Jane) and father (Peter), William's sister (Lindsay) and brother (Francis) and William's biological mother (Stacey) and father (Daniel). All police statements attributed to these people are read by actors.

Thanks to Dennis Martyn for his contribution.
