Sarah Laycock (left) and her daughter, Abigail Miller (age 8, right) were murdered by Abigail's father, a British National Party member, during a psychotic episode.
The thug spared the life of Abigail's four year old sister, as he believed that she was a 'pure Aryan' unlike Sarah and Abigail.
There had been warning signs before - his jealous and controlling nature. The aliens he claimed to see in the back yard. The tinfoil hat he built to block out their signals. The membership in the BNP, a well-known neofascist group.
Below: Nick Griffin, leader of the BNP at the time Abigail and Sarah were murdered. This picture was taken at the American Renaissance Conference. As to why American 'nationalist' conferences invite British fascists... eh, probably the same reason Griffin tried to run off to Hungary when things got too hot in Britain.
