Dorothy Banks makes hearfelt plea for information about the murder of son Duncan, killed in his Skye Road flat

The 39-year-old was found murdered in his Skye Road flat on Monday, September 28 after sustaining multiple head injuries from an unidentified weapon and mother Dorothy says the family will not be able to rest until whoever responsible is brought to justice.

"I would like his conscience to bother him," she said, speaking of the killer. "It could have been an accident, maybe it just happened in the moment, but I really would like his conscience to bother him."

She explained how Duncan had been battling drug addiction and fears that his death is connected to his lifestyle.

"As a mother it is your worst nightmare to bury your child, yet this is our reality," she said. "This has undoubtedly been the most distressing and unsettling period of our lives and it has been made all the more difficult given that we do not know who killed Duncan, and more importantly, why.

"We know that Duncan had his own personal issues and had been continuing to battle drug addiction but to be killed in the manner he was is both cruel and necessary and I believe his spirit will not be at peace until we get justice for him.

"At this time we cannot lay Duncan to rest while the investigation to find his killer continues so I would like to make a plea to anyone who knows something to do the right thing and tell the police anything they know. Someone somewhere must know something, so please come forward."

Mrs Banks said that her son had a "gentle" nature and doted on his family.

"He was a loving son, brother, uncle and friend and his death has left a huge void in this family which we are struggling to cope with at this time," she said.

She added that he wouldn't hurt a fly and if a fight broke out, he would be the one to "go and sit in the corner and actually cry". He was still in contact with his mother every day and came down for dinner most nights, helping her out by taking her rubbish bags along to the bins.

And although she worried for Duncan's drug problems, a factor she believes played a part in his death, she would always try to help him when he asked.

"I think it is related to drugs," she said. "I always knew when he'd been on drugs because his eyes were glazed and the usual signs, he got quite jumpy and jittery.

"He always came down on the Monday when I got my pension. It was always the same, can you help me, can you do me a favour, and I did, because I didn't want him going breaking into people's houses and stealing things. For me, it was far better to give him the money that he wanted."

Speaking of the news of his death, she added: "We were completely shell-shocked, we didn't expect that. I knew that if Duncan didn't actually come off drugs completely, his life would be shortened with the drugs that he took, but just to get the shock of the sudden death, a death like this, you can't come to terms with it and it's very difficult to cope with."
