His body was found floating in a river in Buenos Aires on November 15. A coroner’s investigation ruled out alcohol and drowning as the cause of death. Union spokesmen said it is not known if his disappearance and death are connected to his work. Bonino was a former reporter for the Argentine daily Diario Popular.
