A killer who stood laughing as he set his ex-partner on fire has been sent to a high security psychiatric hospital.
Kevin Marks, 48, stood over mum-of-four Ann Drummond as she rolled around the ground in a bid to put out the fire.
The businesswoman was rushed to hospital but died after more than 80% of her body was covered by burns.
In the hours before the attack, Ann was so concerned by her ex-partner’s poor mental health she met him on June 25 last year.
But Mark then attacked his former partner in her vehicle in a road near his home in Bathgate, West Lothian.
Ann told paramedics that Marks had poured petrol on her and set her alight.
She said he had laughed as she tried to extinguish the flames.
She died at Glasgow’s Royal Infirmary Hospital after doctors concluded her injuries were so severe that she couldn’t survive.
The court heard Marks, now a patient of the State Hospital at Carstairs, south Lanarkshire, had been arrested earlier in the same week in connection with other alleged offences.
Officers were worried by Marks' mental health and he was twice assessed by community forensic nurses.
However, they concluded that he was fit to be released and he later appeared at Livingston Sheriff Court and was granted bail.
Marks then attacked his former partner in her vehicle and poured a liquid accelerant, possibly petrol, over her.
The Crown accepted that Marks' health was so poor at the time of the offence that he was not responsible for his actions.
He was also acquitted of the charges which led to his Livingston Sheriff Court appearance.
Prosecutor Alan Cameron told the court: "Mr Marks has pled not guilty on the basis that he is not criminally responsible for his conduct due to mental disorder.
"That plea, and the existence of the mental disorder in question at the time of the conduct, is supported by the psychiatrists who have prepared reports for the court.
"The Crown accepts the plea of not guilty on that basis."
Judge Collins adjourned proceedings to another hearing at the High Court in Edinburgh on 28 October. The court will then decide how to proceed.
Marks continues to be detained at the State Hospital at Carstairs.
