A man who stabbed a “much loved father, son and brother” to death has been jailed for a minimum of 17 years.

Alan Robertson, 33, struck Allan Doris in the heart outside his flat in Kennishead Avenue on February 13, 2023.

The 43-year-old didn’t recover from his injuries despite a friend coming to his aid.

Jurors heard claims that Robertson did not know how Mr Doris was injured.

But he was convicted of murder in October following a trial at the High Court in Glasgow.

After the verdict, prosecutor Chris MacIntosh told how Robertson already had convictions for violence and possession of offensive weapons including an axe.

Judge Douglas Brown told Robertson when passing his life sentence that Mr Doris was a “much loved father, son and brother”.

The judge added: “The impact of his death had been devastating and their lives will never be the same again.

“Losing him at a relatively young age is bad but to lose him so suddenly due to a brutal violence is almost unbearable.

“Nothing I can say or do can adequately reflect their loss.

“This was a brutal knife attack directed on his chest.

“It must have been plainly obvious that it would likely result in his death.

“The fact he died so quickly reflects the nature of the attack and the severe injuries inflicted.”

The men had initially been in Robertson’s high-rise flat with others before Mr Doris left.

Roberston came out after him and there were claims Mr Doris assaulted Roberston.

The killer was then described by one witness as “absolutely raging”.

He went back to his flat, stormed back out and made a “full force thrusting motion” with his arm towards the chest of his victim.

Mr Doris was heard to groan: “Ah, you have stabbed me.”

As Robertson returned to his home, it was then he was clocked with a “shiny and silver” item in his hand.

Mr Doris begged a friend to get him an ambulance. By the time they got downstairs, he was slumped on the floor of the lift.

Emergency crews arrived, but could not save Mr Doris.

In his evidence, Robertson denied being angry that day. He also claimed not to know how Mr Doris came to be hurt and only recalled seeing him “rolling about the floor”.

Prosecutor Mr MacIntosh, in his closing speech to the jury, said Robertson’s testimony “did not make sense” and was “manufactured” to help him.

Victoria Young, defending, told the sentencing that her client maintains his position from the trial.
