A martial arts expert who bashed his girlfriend to death and dumped her body in bushland has been beaten in a brutal 'retaliatory attack' in prison.
Sayle Kenneth Newson, 43, of Buff Point on the Central Coast, was found guilty of murdering mother-of-two Carly McBride, 31, by the NSW Supreme Court on June 24.
Just four days later, Newson was viciously bashed by three inmates in the maximum security Shortland Correctional Centre in the Hunter Valley.
