A murderer has been jailed for life after setting his wife and stepdaughter on fire and then blaming his dying partner. Seven children were home when a heavily intoxicated Griffiths poured a jerry can of petrol onto Sheahan and then held a lighter against her. I won’t do it,” Griffiths replied, before placing the lighter near the ground and setting Sheahan alight. Flames spread to his 16-year-old stepdaughter and to Griffiths, who extinguished the fire on himself before helping his wife. Emergency services heard Griffiths blaming Sheahan for the fire and telling her: “Why didn’t you stop me, you should’ve stopped me and I should be in jail”.
