Detectives investigating the murder Kieran Doherty in Derry have issued a renewed appeal for information on the second anniversary of his death.
The 31-year-old was shot dead and his body found on the Braehead Road on 24 February 2010.
The Real IRA claimed responsibility for the attack.
Three people have been arrested but so far no one has been charged with Keiran Dohertys murder.
The father-of-one, who was from the Brandywell area of the city, was due to get married three months after his death.
The detective leading the investigation said police still needed assistance and information from the community to make progress.
On the night of his murder, Kieran had been in the family home at Coshowen until around 8pm. His body was later spotted by a passer-by on the Braehead Road at around 10.40pm.
Members of the Doherty family have previously claimed MI5 agents may have been involved in the events surrounding the murder, or that the organisation may have surveillance information that could help the hunt for his killers.
