Posada Carriles celebrated his 80th birthday this month at an undisclosed location in Miami

Luis Posada Carriles, the anti-Castro Cuban militant, celebrated his 80th birthday this month at an undisclosed location in Miami, but many serious legal and political questions about his alleged crimes as a younger man still loom as large as ever. In New Jersey, Posada is the ''target'' of a federal grand jury investigation into the series of 1997 tourist-site bombings in Havana, his lawyer Arturo Hernandez confirmed to The Miami Herald. Posada has long denied any involvement in the bombings. In Washington, Posada's alleged role in the bombing of a 1976 Cuban airliner that killed 73 people is being revisited by a Democratic lawmaker from Massachusetts who plans to hold Congressional hearings on the matter this spring.
