The Clarke family know all too well just how insidious and dangerous coercive control can be.
In February 2020, Hannah Clarke and her three children, Aaliyah, six, Laianah, four, and Trey, three, were killed by Hannah's estranged husband, after he ambushed her car on the morning school run. There, in broad daylight on a normally quiet street in Brisbane, he took the lives of the four people he ought to have loved most. Unwilling to live with the consequences, he also took his own.
