Man who stabbed 43-year-old in heart and left him to die as he pleaded for ambulance found guilty of murder

A criminal who stabbed a man to death is facing a life sentence.

Alan Robertson struck Allan Doris in the heart outside the 33 year-old’s flat in Thornliebank, East Renfrewshire on February 13 2023.

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

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

But, he was convicted of murder on Wednesday 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 adjourned the case until next month when the killer will learn the minimum he will spend behind bars.

Robertson was remanded in custody meantime.

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 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 the 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.

Mercy 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.
