Police investigating the murder of Glenn Quinn have renewed an appeal for information to coincide with what would have been his 50th birthday.
Mr Quinn died after being beaten at his Ashleigh Park home in Carrickfergus, Co Antrim, in January 2020.
Detectives believe he was attacked by a gang of men in his home sometime between January 2 and 3.
The South East Antrim UDA has been blamed for the death.
Mr Quinn, who was terminally ill when he was killed, would have turned 50 today.
Detective Chief Inspector Neil McGuinness said the victim suffered before his death.
“Glenn sustained a violent and brutal attack in his own home, a place where he should have felt safe," he said.
"The unprovoked, violent attack left a defenceless man with serious injuries, including multiple fractures to his ribs, which eventually led to his slow and painful death."
He said Mr Quinn was a popular figure in the area.
"He was well-known and well-liked throughout the community," he said.
"The local community lives under the dark shadow cast by his violent loss of life and the knowledge that those responsible have not been brought to justice."
The PSNI officer said that the "pain and loss experienced by his family is today, as raw as ever".
“The family is frustrated and like any of us, deserve answers and justice for their loved one," he said.
“We are again appealing to anyone with information to search their conscience and come forward.
“We firmly believe there are people within the Carrickfergus community who know the circumstances and know who is responsible for Glenn’s murder.
"These are clearly dangerous individuals."
"We are appealing to the community directly to help us seek justice for Glenn and make your area safer for everyone living there."
Crimestoppers has offered a £10,000 reward for information leading to the arrest and conviction of those responsible for Mr Quinn's murder.
