A murderer has been jailed for life after setting his wife and stepdaughter on fire and then blaming his dying partner. Ms Sheahan, a mother of six, died and her 16-year-old daughter suffered burns to more than 50 per cent of her body as she tired to save her mum’s life. I won’t do it,” Griffiths replied, before placing the lighter near the ground and setting Ms Sheahan alight. Emergency services heard Griffiths blaming Ms Sheahan for the fire and telling her: “Why didn’t you stop me, you should’ve stopped me and I should be in jail”. “Your attack on Ms Sheahan was grievously inappropriate.”Justice Champion jailed Griffiths for life, with 32 years to serve before he is eligible for parole.
