Revealed: Why millionaire Christopher Foster slaughtered his family

Mr Foster shot his family and their pet dogs and horses before setting his £1.2million mansion ablaze in August last year. Earlier, the court had been shown the last actions of Mr Foster, caught on CCTV security cameras on the night of the blaze, as he walked around the grounds of his home in Oswestry, Shropshire, carrying what is thought to be a bucket, a rifle and a battery pack in preparation for setting the fire.
