A robber who kicked and punched a pensioner before taking off with a box of cornflakes and a cottage pie has been sentenced to life imprisonment with a minimum term of 23 years.
John Mackey, 87, was targeted by Peter Augustine after he visited a Co-op store in Manor House, north London, on the afternoon of 6 May.
Earlier in November, an Old Bailey jury found Augustine, 59, guilty of robbery and murder.
He was also sentenced for a theft charge that was dealt with at a magistrates' court.
Augustine did not attend his sentencing at the Old Bailey on Friday, claiming he was suffering from back pain.
Handing out her ruling, broadcast live from the court, Judge Sarah Whitehouse KC said: "I have no hesitation in finding that his non-attendance is voluntary and it is appropriate to sentence him in his absence."
Augustine attacked "gentle, innocent" Mr Mackey "for a box of cornflakes, a pint of milk and a saveloy sausage", Judge Whitehouse said, adding that "I have no doubt that if this defendant was genuinely starving and had asked Mr Mackey for help, this kind, generous gentleman would have" assisted him.
She said: "I have no doubt that the defendant targeted him specifically because he was frail - it was a cowardly act, the defendant has shown no remorse."
Augustine has spent 203 days on remand and therefore has 22 years and 162 days left of his sentence to serve.

He was sentenced to four weeks' imprisonment for theft and eight years for robbery. All three sentences will be served concurrently.
Mr Mackey's niece, Patricia Schan, described her "perfect uncle" as "funny, charming, mysterious, and very definitely mischievous", and went on to criticise Augustine's behaviour during the trial.
Mr Mackey had set off from his home shortly after 5pm wearing a trilby hat, grey Mackintosh coat and carrying a walking stick and black bag.
At 5.12pm, he went into the Co-op where he bought cornflakes, an own-brand cottage pie and Mirror newspaper, which he put in his bag.
Eighteen minutes later, Augustine started to follow the pensioner.
Mr Mackey went into Manor Kebab at 5.36pm and bought sausage and chips as the defendant loitered outside, the trial was told.
The victim was last seen on camera at 5.50pm and Augustine reappeared on CCTV three minutes later carrying what appeared to be the victim's bag, jurors heard.
Passers-by reported seeing Augustine attacking Mr Mackey and searching his jacket as he lay on the ground.
Another member of the public alerted police after she heard a shout of "give me the bag" and saw Mr Mackey lying motionless on the pavement, the court was told.
Mr Mackey, who was bleeding from his head, regained consciousness but was unable to tell officers what had happened.
He was treated in hospital for bleeding on the brain and broken ribs, but died from his injuries two days later.
Police used CCTV footage to piece together events, but the attack was not caught on camera, prosecutor Jane Bickerstaff KC said.
A later search of the defendant's room uncovered what was left of the pensioner's groceries and wrapping from the cottage pie, and sausage and chips.
Augustine was arrested two days after the assault but showed no remorse for his actions while in custody - making a series of threats, acting violently and throwing hot coffee at an officer, the Metropolitan Police said previously.
Ms Bickerstaff told jurors Mr Mackey was 5ft 5in and weighed less than nine stone.
She previously said: "He would have been largely unable to put up any resistance to the attack due to his age and infirmity."
The prosecutor said at the time Augustine was living in "reduced circumstances" and was effectively homeless.
Ms Schan said: "The defendant's behaviour showed complete disdain, disrespect and disregard for the family throughout the trial and caused even further distress from what was already an extremely traumatic experience.
"His refusal to even attend during the trial caused anguish and uncertainty because we did not know what we would be facing on a daily basis.
"He was constantly turning around and looking at us and shouting at us - and frankly terrifying us - from the witness box, which was just a few metres away."
