Jordan Davidson, 26, will serve a minimum of 23 years and four months in prison for the murder of a vulnerable 67 year old man.
The Wrexham man who called himself the Devil murdered a retired restaurateur and described it as the greatest day of his life.
Davidson, who had earlier posed for a mobile phone picture with the murder weapon, a machete which he called “his new toy”, received life imprisonment at Mold Crown Court.
Mr Justice Clive Lewis ruled that he would have to serve a minimum of 23 years and four months years before he can apply for parole.
The judge said: “This was a brutal attack on a vulnerable, frail and defenceless old man.”
There was an intention to kill, he said.
That was clear from the nature of the weapon and the injuries caused with the machete.
He received concurrent sentences for the other offences.
Davidson had gone on on a crime spree of robbery and burglary – and did not stop after he had murdered 67-year-old Nicholas Churton at his flat in Crescent Close in Wrexham.
He went on to rob and seriously injure a man in Chester, attacked a detective was interviewing him and then while on remand at Altcourse Prison slashed a prison officer with a make-shift weapon in revenge for reporting him for drugs years earlier.
Davidson was due to go on trial for murder and a series of other offences at Mold Crown Court last week.
But he pleaded guilty to the murder on March 23 – together with a series of 12 associated offences.

Prosecuting barrister Mr Andrew Thomas QC suggested that he targeted elderly men.
