Gutierrez-Menoyo fought alongside Fidel Castro, but ultimately lost faith in the revolution and became a foe launching commando raids against the island. 

He was imprisoned and exiled, but later came back to Cuba where he became a moderate, pro-dialogue dissident. 

His wife Flor Ester Torres Sanabria told The Associated Press that Gutierrez-Menoyo died at a Havana hospital after suffering a heart attack.
