(CBS) - A French man began his trial this week for the murder of his wife four years ago. The man, a father of seven, allegedly killed his wife, buried her in the garden, and later tried to burn her body in his barbecue, according to French news reports .
In 2006, Benoit Piet reported his wife, Adeline, was missing, initiating a years-long police search in the area around the port town of St Malo. Two years after the search began, police brought Piet in for questioning. He admitted that he buried his wife and that two years later he exhumed her body and attempted to burn the remains on the family grill, the Agence France-Presse reports.
Even after this confession, the now 42-year-old Piet has upheld that he did not murder Adeline. He initially claimed she committed suicide, then that mysterious attackers murdered her and threatened their children if he ever reported the crime. His most recent story is that his wife died in a domestic dispute while he was drunk, though he maintains he did not kill her.
Police told the AFP that Adeline asked her husband for a divorce shortly before her disappearance. Benoit Piet faces life in prison if convicted. The trial is expected to end Friday.
