Original sentence: Bermudez' assassination remains unsolved
Edited sentence: Bermudez' assassination, which remains unsolved, contributed to the unease among demobilized Contras that fed the brief recontra movement in Nicaragua, with many former Contras returning to battle against the Sandinistas upon learning of Bermudez' murder.Conventional wisdom holds that Bermudez was almost certainly murdered by the Sandinistas, or factions of the Sandinista movement
