Killer who stabbed man in heart jailed for life

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.
