Floral tributes have been laid outside the home of Patrick Douglas, who was known locally as Paddy, in Ballymoney where he died following the fire on Tuesday.
There was already a sense of sadness in the town after the news of Paddy’s death but since it has been escalated to a murder investigation, there’s now a sense of shock and disbelief.
Some of the tributes described him as a “gentleman” who was the “best of the best” and will be missed in the town.
Others described him as a “beautiful soul” who left “memories” too beautiful to forget.
One police car remains outside the flat on Main Street.
Appeal for information
Police are appealing for anyone with information to contact them.
Shortly after Mr Douglas’ death, DUP councillor Darryl Wilson said he was a “well-known and liked character from our town” and sent condolences to his “family, friends, and all those affected by this devastating loss”.
