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 Miss Watt.

The 55 year-old 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 Miss 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.

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.

The trial heard the relationship appeared to have ended days before the killing.

But, he turned up at Miss Watt's house on June 2 after she got home from work.

Brown said he then flipped when Miss Watt made a “gesture” with her hands that they were finished talking.

The former soldier fled the scene and later drove to Dumfries-shire.

He claimed he planned to take his own life, but police later found him in his car.

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.

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

Brown will be sentenced on July 6 in Edinburgh.
