Bertrand Lucien Bruno Cantat is a French songwriter, singer, and convicted murderer known for being the former frontman of the rock band Noir Désir. In 2003, he was proven guilty without a doubt and convicted of the murder of French actress Marie Trintignant, which occurred in a hotel room in Vilnius. To some controversy, Cantat returned to Noir Désir after his release from prison in 2007, playing with the group until it disbanded in 2010. He subsequently formed a musical duo with Pascal Humbert, calling themselves Détroit.
