Estranged husband Claud Mubiangata, 38, killed his two daughters, Alpha, 12, Cindy, nine, and two sons, Chriony, seven, and Aaron, three, by setting fire to a silver Nissan Primera, then killed himself. The tragedy happened three-and-a-half weeks ago, after Mr Mubiangata collected the children from their mother's home for what was meant to be a trip to see the film Scooby Doo.
