A killer once dubbed one of Britain’s most wanted fugitives has been jailed for at least 26 years.
Shane O’Brien, 31, evaded police for three-and-a-half years after he slashed Josh Hanson’s neck in Hillingdon, west London, on 11 October 2015.
He fled the UK, changed his appearance and moved around Europe before his extradition from Romania in April.
O’Brien, who jurors found guilty of murder last month, was given a life sentence at the Old Bailey.
CCTV released during the trial showed 21-year-old Mr Hanson clutching his neck and stumbling as blood poured out of a 37cm (14.5in) wound.
Meanwhile, O’Brien was seen “calmly” walking out of the bar and later boarded a private plane to fly to the Netherlands, the court heard.
Sentencing the father-of-two, Judge Nigel Lickley QC called it “a grotesque, violent and totally unnecessary attack on an innocent man”.
“The reason why you behaved in such a way may never be fully explained. You, however, know the reason,” he said.
In a victim impact statement, Mr Hanson’s mother Tracey described her son as being “considerate, kind and generous”.
“He was taken from us in the most horrific way possible – suddenly, abruptly, viciously and violently,” she said.
The victim’s sister, Brooke, said the 21-year-old “was not just my brother, he was my best friend”, and described his “infectious smile” and “magical presence”.
She told the court she had suffered from anxiety and post-traumatic stress since the killing and found herself always wondering if she could have protected him from the “evil” that took him away.
During the trial, O’Brien had claimed he felt threatened by Mr Hanson’s “very aggressive body language” and had only meant to scare his victim.
There were angry shouts of “coward” from the public gallery as he was led away from the dock.
