A man murdered his two daughters, one 5 years and 2 months old and one 7 months old. He placed them in a 750 degree Celsius aluminum liquefying furnace. Teeth and many fragments of the severely burned bones were recovered. However, at first the bone fragments did not furnish proof that two persons had been put into the furnace. Age estimation of the teeth burned in liquefied aluminum was based on the maturity of the teeth and the degree of absorption of deciduous teeth roots. The admixture of permanent teeth and deciduous teeth led to the presumption that they had come from more than one person. Figures, references
