A son has paid tribute to his "sweet and lovable" mother as a teenager who raped and killed her in her own home was jailed for more than 12 years.

Marie Reid, 63, was found five days after being attacked by Jay Soso, 18, who had known his victim since he was a young boy and was "like a grandson" to her.

Soso, who pled guilty to rape and culpable homicide, was jailed for 12 years and eight months at the High Court in Edinburgh, with the judge, Lady Dorrian, ordering him to be supervised for five years following his release.

Paul Reid, 31, the victim's son, described how Soso had offered his condolences to the family following the brutal killing.

Mr Reid said: "Knowing that he shook my hand and gave me condolences, that makes me even more angry towards him."

On the violent loss of his mother, he added: "I just hope it never happens to anybody. It's hard to cope with, I'm struggling myself in life now. Losing my mum has been so hard.

"I knew Jay since he was maybe eight or nine. I couldn't believe that Jay would do such a thing like this, he didn't seem the type. My mum treated him like a grandson."

Mrs Reid's body was discovered on November 15, 2010 after neighbours became concerned they had not seen her for a number of days.

She was found in bloodstained nightclothes, lying on a sofa in the flat where she lived alone in Edinburgh's Easter Drylaw Way.

Thanking police and prosecutors for their work, Mr Reid, who attended the court with his sister, Jacqueline Sanderson, added: "I'm glad the door's been shut now. Hopefully I can get my life back together, Jacqueline can get her life back together and we can just get on with it, and my kids can now get on with their lives as well."

Gordon Sanderson, 54, the victim's son-in-law, of North Berwick, said the family was very happy with Soso's sentence.

He said: "The way I see it now, he's away and other women in the same situation are going to be safe from him. He's off the streets and the public's safe.

"Marie was so quiet, friendly and trusted people. She didn't deserve to go the way she did. We can't fathom what he was thinking to have actually done it."

Soso and his mother used to live next door to Mrs Reid. In early 2008, they moved to Hartlepool in north-east England but he returned to Edinburgh by June that year and eventually got a flat in the Drylaw area.

At the time of the attack, he was single and worked locally as a fishmonger.

The court heard Mrs Reid suffered from a number of significant medical issues and her health was more like that of an 80-year-old.

Concerns were raised after she had not been seen for several days. When housing support officers entered the home, they found her dead in her lounge.

Police initially thought her death was not suspicious, but post-mortem examinations were carried out after the victim's son and other family members voiced concerns.

Analysis revealed Mrs Reid had been raped on the evening of November 11, that she had died at that time, and that the rape had contributed to her death. Soso's DNA matched samples taken from her body.

He was originally charged with murder, but his plea of guilty to the reduced charge was accepted.
