A drug dealer has been jailed for the "senseless killing" of a father who was stabbed as he shouted "you've got the wrong guy".
Daniel Quinn, 28, stabbed Daniel Fitzjohn in Northampton in June, after an earlier scuffle in a newsagents.
At Northampton Crown Court, Quinn was convicted of murder and jailed for life with a minimum of 27 years.
Parminder Sanghera, 25, was jailed for 10-and-a-half years for manslaughter.
The pair, from Wolverhampton, were in Northampton because cocaine dealer Quinn sold drugs in the town.
Mr Fitzjohn, 34, had never met him but a man he was with had bought drugs from him, the court was told.
Mr Fitzjohn and his friends were involved in an "altercation" with Quinn at Fairfield News in Kingsley at about 21:25 BST, in which the murder victim intervened and punched Quinn to the ground.
Quinn drove his Mini at the group before finding Sanghera nearby and driving back to the scene armed with a kitchen knife and machete.
Quinn was in what the judge described as "a blind rage".
The group scattered when they saw Quinn and Sanghera, but Mr Fitzjohn was spotted later, at which point Quinn got out of the car and stabbed him twice, the court heard.
Witnesses reported Mr Fitzjohn shouting "you don't know me, you've got the wrong guy" before his death.
Quinn went into hiding in Wales but was identified from dash cam footage from a taxi driver, who a judge said should be awarded £1,000.
The killer later handed himself in to police.
In a victim impact statement, Mr Fitzjohn's father Roy said his son's death had left him angry and "numb".
Judge Rupert Mayo told Quinn: "Mr Fitzjohn has been described as being in wrong place at wrong time.
"It sets his senseless killing into the right context."
