Re: Jonathan Donne, a convicted killer who murdered 67 year old John 'Jack' Williams after robbing him in his own home has been jailed for life by Swansea Crown Court.<br />
Donne, 42, from Swansea, was found guilty of the robbery and murder.<br />
Mr Williams was tied up and battered in the living room of his Swansea home in March 2018 because Donne thought he had a large quantity of drugs and money.<br />
He was told he must serve at least 31 years before he can be released from prison.<br />
He was also given a 15 year sentence for robbery, which will be served concurrently.<br />
Donne went to Mr Williams's house because he needed money where he hit and tied Mr Williams up, but insisted he was alive when he left.<br />
Mr Williams suffered serious brain and head injuries in the attack.<br />
The victim had been growing and selling cannabis and Donne thought he would have drugs and cash he could steal.
