The judge told Aymer he was guilty of a "wicked act of mindless violence"
A teenager has been jailed for life for stabbing to death his girlfriend's 22-year-old brother in Brighton.
Judge Richard Brown told Aaron Aymer, 18, at Lewes Crown Court, that he was one of the most dangerous men he had ever come across.
David Stunell, of Desmond Way, Brighton, was stabbed during an incident in the city on 28 July 2007.
Aymer, from Wapping in east London, was sentenced to life with a recommendation that he serve at least 16 years.
Judge Brown said: "The fact remains this was a horrendous and wicked act of mindless violence.
"You have taken the life of a thoroughly decent and hard-working young man and devastated the life of his family."
People like him should not be on the streets
A jury at Lewes Crown Court found Aymer guilty in April of murdering David Stunell.
The court heard a row broke out in Montpelier Crescent where Mr Stunell confronted Aymer about his relationship with his sister, Hayley Stunell.
As Mr Stunell bent forward to speak to Aymer, who was sitting in the passenger seat of Hayley's car, the teenager slashed his neck with a kitchen knife.
An off-duty doctor and a member of ambulance staff tried to stop the bleeding but Mr Stunell was later pronounced dead at the Royal Sussex County Hospital.
Aymer, who had denied murder, claimed he was acting in self defence and had stabbed Mr Stunell accidentally and then fled in panic.
'Lie after lie'
His defence counsel Nigel Sweeney read out a statement in which Aymer expressed guilt and regret for his actions.
But during the sentencing, Judge Brown said he had an "appalling record" and had told "lie after lie" to avoid being found guilty.
Outside the court Hayley Stunell, 19, said: "People like him should not be on the streets."
David Stunell was stabbed to death in July last year
Aymer was also given six years detention and four years extended license for wounding with intent, to be served concurrently.
Det Ch Insp Graham Pratt, who led the investigation for Sussex Police, said: "David's mother Carol, his family and his many, many friends have had their lives devastated by this needless act of violence."
Brighton and Hove's police commander, Ch Supt Paul Pearce added: "Aaron Aymer, who was visiting his girlfriend in Brighton at the time he stabbed Mr Stunell, was an habitual carrier of knives with a long history of using them.
"It is quite right that Aymer has been handed this very lengthy sentence for his actions which resulted in such a calculated murder."
