A FORMER soldier obsessed his ex-partner had cheated on him has been convicted of her murder.

Gary Brown stabbed Alyson Watt 42 times at her home in Paisley, Renfrewshire, in June last year.

He also carried out a ferocious hammer attack on an innocent 16-year-old boy who stayed with Ms Watt.

Brown, 55, struck after finding a text months earlier that the Barnardo's charity worker may have kissed another man.

Brown fled after the horror attacks – but Ms Watt was able to whisper to a neighbour the ex-squaddie was the culprit as she lay dying.

He denied murder, insisting he was suffering from an “abnormality of the mind” at the time.

Brown was said to have a personality disorder.

But, he now faces life in jail after jurors today/yesterday rejected his claims.

He had earlier pled guilty to the attempted murder of the boy, who now needs round-the-clock care.

In connection with the killing, Brown's legal team had urged jurors to convict him of the lesser charge of culpable homicide due to diminished responsibility.

It emerged after the verdict that Brown had previously been fined for a violent road rage incident.

Brown – who showed no emotion – will return to the dock next month.

The former Scots Guard had previously served during the Falklands War.

His lawyer told the court Brown was “a very troubled man resulting from his childhood and his involvement in the Falklands conflict.”

Brown will be sentenced on July 6 in Edinburgh.
