Two petrol bombers who killed four young children in an arson attack were seen laughing and joking just hours before the murders.
Zak Bolland, 24, and David Worrall, 26, could face a fresh murder charge after the children's mother, Michelle Pearson, died 20 months after the tragic fire.
Their trial was shown chilling CCTV footage which captured the killers filling up a jerry can with £1.50 worth of petrol shortly before the December 2017 attack in Salford, Greater Manchester.
Earlier, the pair were seen laughing and joking as they bought beer from a Londis - with Worrall fist-bumping the shopkeeper - along with Bolland's then-girlfriend Courtney Brierley.
