Malcolm McHaffie, the deputy chief crown prosecutor for CPS London, said:
“A few days before she was killed, Sian Blake had been told that she had motor neurone disease and that it was terminal. Tragically, Arthur Simpson-Kent’s actions on the night of 14 December 2015 prevented Sian’s family
offrom spending precious remaining time with a much loved sister, daughter and mother. It also wiped out a future generation of the family.
“Simpson-Kent went to great lengths to conceal his crimes. He misled friends, family and the police about what he had done and where Sian and her children had gone. Even more callously he suggested that Sian and he had entered into a pact to end all of their lives because of her condition. This was not true. In fact Sian had been making enquiries about schools for the children and had been considering moving to live with her family without him. These were brutal, cold-blooded murders of his partner and children, whose trust he grossly breached. We made this clear to the court today to assist the Judge in deciding the sentence.
“I hope that the sentence passed today gives Sian’s family some small amount of comfort at this very difficult time. I would also like to thank the Ghanaian Authorities for their assistance in relation to the arrest and extradition of Simpson-Kent.”
