Brother claims slain American pursued a 'diabolical' plan to free Cuba

Michel Ortega Casanova, one of 10 people on a Florida-registered speedboat that clashed with Cuban forces in an attempted infiltration of Cuba, was described by his brother as driven by an obsessive and 'diabolical' push to free Cuba; four people were killed and six injured. U.S. and Cuban authorities are investigating passenger identities and whether any were U.S. citizens or residents, amid broader security and terrorism-related concerns around the incident.
