A teenager has been found guilty of manslaughter after starting a fire that killed four siblings in Freckleton, Lancashire.
Four-year-old twins Holly and Ella Smith and brothers Jordan, two, and Reece, 19, died on 7 January last year.
Dyson Allen, 19, of no fixed address, denied starting the fire in a bedroom wardrobe at the dormer bungalow.
Mark Hutton, group manager for Lancashire Fire and Rescue, said the blaze became "unsurvivable" within minutes.
