A man has been jailed for life for shooting dead a father-of-four on his doorstep in front of his family.
The judge recommended Coleman serve a minimum of 22 years
Dwayne Coleman, 23, of north London, was found guilty at the Old Bailey on Wednesday of murdering Alan Musgrove in Forest Gate, east London.
Coleman shot Mr Musgrove as he answered the door to another man dressed in a pizza delivery jacket in July 2002.
He was also jailed for 13 years for conspiracy to rob. The judge said he should serve a minimum of 22 years.
The court heard the men thought Mr Musgrove was a drugs dealer who kept a large amount of money at his home.
The men also believed they would be able to steal drugs in what they considered an easy operation.

Judge Sir John Blofeld said: "This was a planned robbery for gain, carrying a loaded firearm to the man's own home after dark.
"We cannot say whether there was any partial truth in the belief in these men's minds or whether it was a grave error but whether it was one or another does not matter."
The prosecution accepted that the man dressed in the pizza delivery jacket, Rasnow Warburton, had no part in the shooting.
Warburton, who admitted conspiracy to rob, denied knowledge of Coleman having the gun and gave evidence for the prosecution during the trial.
He will be sentenced at a later date.
Coleman had denied murder and conspiracy to rob Mr Musgrove.
