MIAMI (AP) - U.S. immigration authorities are investigating after a boat carrying 15 people capsized in the waters off Miami.
    
Four people died when the small boat capsized early Wednesday. Eleven survivors were taken into federal custody.
    
Immigration and Customs Enforcement spokesman Nestor Yglesias said Thursday that two people will face charges for attempting to illegally smuggle people into the U.S.
    
Yglesias says a criminal investigation is continuing, but additional details were not immediately available. It was not clear where the remaining survivors were detained.
    
Coast Guard officials said Wednesday they were working to confirm that the people on the boat were Haitian and Jamaican.
    
Migrants routinely attempt to illegally reach Florida's coast in overloaded or unseaworthy vessels, often through established smuggling networks that include islands in the Bahamas and Turks and Caicos.
