A man who battered a fellow resident to death at a homeless hostel will serve a minimum of 13 years before he is eligible for parole.
Earlier this month Somes McFarland, 28, who has Asperger's syndrome, was found guilty of murdering 51-year-old Peter Oates. The killer was drunk at the time of the attack.
Following a week-long trial McFarland pleaded not guilty to murder.
The jury rejected his plea of "manslaughter due to diminished responsibility".
Yesterday he returned to court to receive the mandatory life sentence for murder and to hear details of the minimum term he will serve.
Mr Oates, an alcoholic who was described as being "frail" at the time of his death, died from a brain injury in his room where the murder happened.
Jurors heard that McFarland used his fists and feet as weapons to attack his victim.
Mr Oates suffered 19 fractures to his ribs where McFarland had jumped up and down on him, as well as injuries to his head and neck.
The sickening assault took place at the Henley House hostel, Fore Street, Pool, beginning late on March 24 and continuing into the early hours of the following day.
CCTV images captured McFarland entering and leaving Mr Oates' room a number of times on the night.
The Honourable Mr Justice Burnett said McFarland had kept demanding "respect" during the assault while repeating the words "I'm a killer".
The judge said the attack was "sustained and repeated". He emphasised that the 13-year term was a minimum sentence and the parole board would only release him when they were sure he was ready to leave.
