A MAN whose wife was killed by their 13-year-old foster child has called for a close investigation into social work services.

Bryan McKenzie, 40, outlined a series of concerns about the support they were given by Glasgow City Council social workers before his wife Dawn, 34, was stabbed to death by the teenager in June 2011.

Speaking at a Fatal Accident Inquiry into Mrs McKenzie's death, Mr McKenzie said: "I have thought about it for four years and I can't think of anything we could have done differently."

Procurator Fiscal depute Carrie Macfarlane asked if others involved in the boy's care could have done anything differently.

Mr McKenzie said: "I felt we were given very little information, particularly information we should have had to allow us to care for him, to know about his situation.

"It's just hearsay now, I could say a hundred things now, but at the end of the day what has happened has happened."

I feel we were let down badly by the social services.

"I feel that the contact with the social work was poor and I think the (main social worker's) attitude toward the placement was lacklustre. I thought his attitude was lackadaisical."

Mr McKenzie said the fostering agency Foster Care Associates (FCA), now known as Core Assets, should also have given them more information about the boy's background.

When the couple finally received a background report about two months after the placement started, it emerged that when he was taken into care the boy had been sleeping on a trampoline, had no shoes, was living in a house frequented by drug addicts and had been subjected to "frequent acts of violence".

Mr McKenzie told the inquiry that the day his wife was killed they had confronted the boy about arriving home three hours late after school on the last day of term before the 2011 summer holidays.

They abandoned their regular Friday-night activity of DVDs and "junk food" and the boy was sent to bed early.

He was already aggrieved about the confiscation of his phone and laptop after it emerged that he had been holding conversations with his birth family online.

Mr McKenzie said: "I decided to spend some time with Dawn's brother so we had dinner and I left the house about 7pm.

"He seemed okay and Dawn was sitting on the couch. We had a discussion about what had happened and he seemed to accept it."

"I said 'see you later wee man', ruffled his hair, gave Dawn a kiss and I left," he said.

"I wouldn't have left the house if I had any concerns, no way."

Mrs McKenzie's mother Ray Byrne, 64, was frequently reduced to tears as she recalled her daughter's love for children, her desire to foster and how she was ultimately "let down" by social workers.

She said: "She was my friend and my confidante as well as my daughter. I miss her every day."

The boy was detained for seven years after admitting culpable homicide on the grounds of diminished responsibility.

The inquiry was adjourned until Thursday.
