The man accused of the murder of an Irish pensioner in London told a judge last May that he did not want bail because he was "guilty".
Peter Augustine, 59, was not present for the fifth day of his trial at the Old Bailey.
He denies the charges of murder and robbery.
John Mackey died on 8 May, two days after he was attacked as he walked home from his local supermarket and takeaway in north London.
He suffered blunt force impacts to his head and chest.
The 87-year-old bachelor was originally from Callan, Co Kilkenny.
In agreed facts, read out to the court today, the jury was told that 59-year-old Peter Augustine appeared in court on 13 May in connection with the charges of murder and robbery.
When the matter of bail was raised, Mr Augustine replied "I don't want bail".
A transcript of the exchange was read out as follows:
Augustine: "Your honour, I don't want bail."
Judge: "You don't want bail."
Augustine: "I don't sir, because I know what I did."
Judge: "Okay, alright."
Augustine: "I don't want bail, I'm guilty."
The court also heard witness statements from first responders who attended to John Mackey on 6 May, the day of the alleged attack.
They spoke of how Mr Mackey was "dazed" but "conscious" when they arrived at the scene.
However, the police officer who travelled with Mr Mackey by ambulance to Whittington hospital recalled that his "ability to converse deteriorated" during the journey.
Mr Mackey died in hospital on 8 May from severe head injuries.
The pensioner had purchased groceries and a takeaway prior to the attack. The groceries comprised a cottage pie, cornflakes and Daily Mirror newspaper.
Peter Augustine was staying at the nearby Beaconsfield Hotel, which was paid for by his sister.
When Mr Augustine was arrested there on 8 May, an empty cottage pie container, packet of cornflakes and Daily Mirror newspaper dated 6 May was found in his hotel room.
An empty takeaway container was also discovered.
Mr Augustine denies the charges of murder and robbery.
When he appeared in court on the first day of his trial he shouted from the dock, "I never hit him", adding, "I took the bag and I ran".
A psychiatric defence is not due to be raised in the case.
The trial continues at the Old Bailey next week.
