A teenager has been jailed for life for the murder of a young father outside his home and in front of his family.
Tucker said he only meant to scare Mr Woodhams
Bradley Tucker, 18, shot Peter Woodhams, 22, in Canning Town, east London, last August.
Months before his death, the victim was stabbed in the neck and slashed across his face. An inquiry is under way into the police handling of the incident.
Tucker, of Canning Town, who was found guilty last month, said he only meant to scare his victim.
He will have to serve a minimum of 25 years before he can be considered for parole.
Mr Woodhams's death was the "final chapter" of a bullying campaign, a trial at the Old Bailey heard.
He was shot when he confronted a group of youths over smoking cannabis outside a local supermarket.
Mr Woodhams's fiancée Jane Bowden, 24, told the court in a statement the killing had turned their life into a nightmare.
She said her three-year-old son Sam, was convinced his father was a star in heaven and looks at the sky and says: "Look, there is daddy looking down on me."
Mr Woodhams's son Sam "still believes his father is coming back"
The judge, Recorder of London Peter Beaumont, told Tucker: "You were not provoked in any legal or real sense to do what you did.
"You perceived disrespect. You feared loss of face in a challenge that you perceived from the man you killed - a challenge to the standing you felt you had in the eyes of the people whose respect you sought.
"To meet that challenge, you acquired a gun, you followed a man to his home in broad daylight and, in front of his home, you shot him repeatedly."
Tucker will have the 221 days he has already spent on remand deducted from the 25 years minimum term he must serve, at which point it will be decided whether he is fit for release.
A 17-year-old boy, who cannot be named for legal reasons, was cleared of murdering 22-year-old Mr Woodhams.
Nine police officers face an misconduct inquiry by the Independent Police Complaints Commission after claims they did not carry out a thorough investigation into the earlier stabbing incident.
