Police investigating the "cold-blooded" shooting of Liverpool man Jamie Starkey have appealed for information on the first anniversary of his murder.
The 21-year-old was shot several times as he left his house in Higher Lane, Fazakerley, on 2 December 2012.
Four men have been arrested on suspicion of murder and remain on bail.
Detectives said they believe members of the criminal fraternity hold vital information and appealed for them to "search their consciences".
Det Ch Insp Alyson O'Donnell said: "This was a cold-blooded, calculated shooting and there is no doubt that the offender meant to kill Jamie.
"Jamie's family have been deeply affected by his loss and are trying to face up to another Christmas without their son and brother.
"Someone out there knows who did this and can help them find some closure."
