Killer who stabbed man in heart jailed

Alan Robertson stabbed 43-year-old Allan Doris to death

A killer who stabbed a 43-year-old man to death in a "brutal" attack has been jailed for a minimum of 17 years.

Alan Robertson, 33, knifed Allan Doris in the heart outside his flat in the Kennishead area of south Glasgow on 13 February 2023.

Mr Doris died a short time later at the scene despite a friend coming to his aid.

Robertson was convicted of murder following a trial at the High Court in Glasgow.

Allan Doris was a "much loved father, son and brother"

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".

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

The judge said: "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."

'Absolutely raging'

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

Roberston came out after him. There were claims Mr Doris assaulted Robertson.

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 the victim.

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.

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.
