The daughters of an elderly disabled man who died after being attacked in his bedroom have offered a cash reward to catch those responsible.
Eugene Carr, 73, died in hospital in November 2015 following the violent attack at his home in Bessbrook, Co Armagh, in August that year.
He had been asleep in his bed when three masked assailants stabbed him 15 times before leaving him for dead on the floor of his bedroom. Four years on, those responsible have never been caught.
Now, two of his daughters have made a fresh appeal for information on the anniversary of his death and are offering a cash reward to help bring his attackers to justice.
They have offered £10,000, which charity Crimestoppers has matched to create an overall sum of £20,000 for information that will lead to convictions.
Patricia Bennett and Michelle Finnegan said their grief is made worse by knowing their father’s killers remain at large.
"Our dad Eugene was cruelly taken from us four years ago and a day hasn't gone by since we don't miss him or remember the trauma," they said.
They both have thanked Crimestoppers for their donation.
The PSNI has described the investigation as "difficult".
In a statement, Detective Chief Inspector Eamonn Corrigan said Mr Carr had been stabbed 15 times in a "vicious and unrelenting" attack.
The detective added that he believes the answers to Mr Carr's murder lie within the Bessbrook community and he has appealed for anyone with information to come forward.
