Guyon de La Roche, killed by his brother-in-law
Back in 1109. Guy de La Roche was murdered. The abbot Suger wrote about this news story in his book Vie de Louis VI (Louis VI's Life): Guy was a nice man, sweet and gentle. He did good around him.. But he had enemies, even in his own family! Like his brother-in-law, Guillaume, ″A Norman, an unrivaled felon.″ One day, Guy was attended Mass: the traitor rushed in his back and stabbed him. Stabbed, stabbed! Again and again. He killed him, with his wife and kids, with an unequaled violence, ″by crushing their skulls on the rock″… And the castle was seized by Normans!
