“I’m not the one who has the problem. I’m just doing what I’m told.
“I by no means even thought my spouse was able to doing something like this.”
The next morning, February 19, he was again seen on CCTV filling his car with fuel.
A little more than an hour later, he doused Ms Clarke and their three children in petrol whilst they were inside a car, before setting them on fire.
