A FAMILY today told of their daily heartache since their dad was killed in a deliberate fire in 2003 while his killer has still not been caught.

Ronald Kerr died in a blaze in his home in Glasgow's Cardonald four years ago.

Firefighters managed to pull the 49-year-old from the blaze in his Lamberton Drive home but he was pronounced dead a short time later.

Police believe the fire was started deliberately and are treating his death as murder.

But no one has yet been charged with the crime and son Ronnie, along with Mr Kerr's stepdaughter Gina Campbell, 33, her three sons and the rest of the family, say they cannot move on until those responsible are caught.

Ronnie, a 26-year-old electrician said: "I can't give up hope that my father's killers will be found that's all I have to cling on to.

"I just pray one day there will be a breakthrough that will move the police probe on.

"It might be four years on, but I live with this day to day and as a family we cannot move on until we have answers. Someone out there must know something and I urge them to come forward."

On Sunday, which marked the fourth anniversary of Mr Kerr's death, the family laid flowers at his graveside.

Ronnie added: "Dad had battled through life as he was born with a kidney disease. For us to lose him in this way is even harder to take.

"He was registered disabled and I was his carer.

"Growing up it was just the two of us for a long time and I was just getting on my feet when this happened."

Detectives today renewed their plea for anyone with information to come forward.

Detective Inspector Frank McEwan, of Helen Street police station, Govan, said: "I would appeal to the public to think if they have any information, no matter how insignificant it may seem, regarding this.

"Someone has that crucial piece of information and for whatever reason has still to contact police.

"It may be that that person assumes that we already know such details and I would like to stress that people shouldn't assume what my officers know, but should come forward as a matter of urgency."
