His wife Agnès Dupont de Ligonnès and their four children were murdered at an undetermined date in early April 2011, and their bodies were found buried in their garden on 21 April. An international manhunt is under way for a handsome, aristocratic Frenchman police believe may have shot and killed his wife, their four children, and two dogs, burying them all in the garden of their home in Nantes, France.
