Xavier Dupont de Ligonnès was raised thinking that strength, wealth and success were key to life. Xavier's family was a known noble aristocratic family that dated back to mid 18th century France. Xavier married Agnès Hodanger in 1992 and Xavier adopted Agnès' two year old son Arthur. The couple had three more children: Thomas, Anne and Benoît. The family resided in an upper class neighborhood in Nantes, France. Xavier was a successful businessman and Agnès worked at a Catholic school. On April 21, 2011, french police entered the home of the Dupont de Ligonnès family for the sixth time in two weeks. Relatives and neighbors hadn't seen or heard from the family, which was unlike them. In the first five searches, police found nothing that was suspicious. This time, they made a horrific discovery. In the backyard, under the terrace was a hole containing large plastic bags full of bodies. They were the remains of Agnès, Anna, Arthur, Benoît and the family's two dogs. Thomas, believed to be killed the night after the rest of the family, was buried in a separate grave. They were believed to have been killed between April 3 and 5. Xavier's remains were nowhere to be found, making him a suspect immediately.  Between April 10 and April 22, Xavier was seen on security camera withdrawing money from his bank account. There wre also several charges on his credit cards for food. His car was found the next day in a parking lot of a hotel over 80 miles away. Investigators learned that Xavier was not as successful as thought and the family was almost out of money. It's believed that Xavier killed his family and fled. His whereabouts are unknown to this day.
