At one point Stephen Seddon shouted from the dock, insisting he was innocent. But the judge told him to keep quiet, and continued his sentencing:
One can only imagine the horror of your parents' last moments in this life, when they realised what a monster their son, whom they loved, had become.
Mercifully their deaths were swift. The reason for the attempted murders and the murders was greed. You needed money. You had lost your job. You had a mortgage. You had a family to support. You had some grand plans.
Despite the fact that your parents had always been very generous in supporting you, you wanted more and you wanted it now - hence the plan to kill them and get your inheritance up front.
The attempt at murder having failed, you decided on a more ruthless and definitive method of killing. You obtained a sawn-off shotgun from criminal associates.
