Detective Inspector Vicky Short, who led the investigation, said:
The physical and mental abuse meted out by the Rooke family on a highly vulnerable man plumed the depths of depravity.
David, Donna and Jamie Rooke abused Mr Kinsella for their own pleasure until his spirit and will to stand up for himself and fight back was crushed.
It has hard to understand how any human being could treat an individual in such a grotesque, callous and inhuman manner.
I am confident that if we had not received that phone call that day last July we would have been investigating a murder.”
