MIAMI (AP) - The daughter of a prominent Cuban dissident who died in a car crash says her family decided to seek refuge in the U.S. after facing continued repression on the island.
    
Rosa Maria Paya and her mother spoke with reporters in Miami Tuesday.
    
Paya traveled throughout Europe and the U.S. in April to push for an international investigation into her father's death.
    
Oswaldo Paya was killed in a car crash in 2012. His daughter says witness accounts, text messages and other evidence raise questions about the Cuban government's official account.
    
Rosa Maria Paya returned to Cuba, even though she said her family had been threatened.
    
She said Tuesday the attacks and vigilance against her family and others involved in the movement her father started had intensified.
