A man who murdered two people at a party with the same bullet has been jailed for a minimum of 20 years.
Davis was trying to stop people leaving a New Year's Eve party
Iain Davis, 27, of Brixton, south London, shot DJ Ashley Kenton, 22, in the neck in an argument at a 2002 New Year's party in Hackney, east London.
The same bullet then passed through a partition wall to kill Wayne Mowatt, 26, a party guest in the next room.
Davis was given two life sentences at the Old Bailey on Friday, after being found guilty of the murders in May.
Davis's family and the victims' friends clashed when the verdicts were given last month but were banned from attending the sentencing.
John Bevan, QC, prosecuting, told the court during the trial that trouble started at the party at about 0900 GMT when Davis tried to stop people leaving a flat in Shore Road.
Mr Kenton, who had been playing music under the name DJ Creation, pushed Davis away after he tried to punch him, he said.
During the row a man passed a loaded gun to Davis, said Mr Bevan, which he used to shoot Mr Kenton through the neck, severing an artery.
The bullet also hit Mr Mowatt, who was in the next room. He collapsed in a pool of blood from a wound to the side of his head.

Judge David Paget told Davis: "The really serious aspect of this case is that you and your companion had a loaded firearm which was ready for use at a moment's notice.
"You have devastated the lives of the victims' families and you have ruined your own life simply because you did not get your own way and you were made to look foolish."
Davis, who left the UK shortly after the killings, was arrested at Long Beach airport in California for immigration offences in August last year.
He was deported to England and was arrested on suspicion of murder last September.
Det Chief Con Andy Shrives, who investigated the murders for the Metropolitan Police, said: "This was a cowardly attack that appears to have been sparked simply by the fact that Davis believed Mr Kenton was being disrespectful to him by wanting to leave the party early.
"We are obviously pleased at Davis' successful conviction."
He said police were still keen to trace one suspect in relation to the case.
Anyone with information on the whereabouts of Martin Harvey, who is 45, black and known to frequent the Haringey area should contact the Metropolitan Police.
