Police in the North have issued a renewed appeal for information about the murder of a man in Derry last year.
Today is the first anniversary of 31-year-old Kieran Doherty - who was found dead on the Braehead Road.
He had been shot in an attack which has been claimed by the Real IRA.
The detective leading the investigation said police inquiries were continuing but that they would be substantially progressed if there was more information coming from the community.
Detective Chief Inspector Ian Harrison says police are still working on the case, have made progress, but not enough to bring charges.
Inspector Harrison says there are people in the community who know what happened to Kieran, and who killed him adding It is to those people that he once again make this appeal.
Kieran Donnely had been in the family home at Coshowen until about 8pm on the Wednesday evening of 24 February when he went out.
The next sighting of Kieran is when a passer-by found his body on the Braehead Road around 10.40 pm.
Police want to speak to anyone who was on that road anytime from 8pm that evening and saw anything suspicious or who knows of Kieran's movements after he left his home.
