Did some research on this possible suicide and found this on Facebook. It is written in Portugese and translated by Google.
It seems the captain on this flight went to his manager two days before the fatal flight and asked to be replaced because he was not fit to fly. He had problems in the relationshipo with his wife. LAM refused to substitute the captain. His wife left him 15 days before the crash. The reason for not substitute is unclear because of not very good translation of Portugese language. Maybe someone can translate.
