Witnesses have told an inquest of Hannah Clarke's chilling screams, pleas to save her children and her efforts to fight her estranged husband after he poured fuel in her car and lit it.
Ms Clarke and her three children were doused in petrol and burned alive by Rowan Baxter in Brisbane on February 19, 2020.
She and children Aaliyah, six, Laianah, four, and Trey, three, had just left her parents' Camp Hill home about 8.30am when Baxter climbed into the passenger seat of her car armed with a knife and can of petrol.
