A CNN report seems to confirm that the Hakkens have arrived in Cuba.

Quote
... A man on a boat at a Havana marina told CNN's Patrick Oppmann he is Josh Hakken, the U.S. man accused of kidnapping his sons and sailing them to Cuba.
He declined to answer questions, and Cuban security asked a CNN reporter to leave.

The man, who fit Hakken's description, was with a woman who fits the description of his wife. Both were aboard a blue sailboat named "Salty." The CNN reporter also saw one child on the boat.

Hakken, a Louisiana man who lost custody of his two young sons, is accused of abducting them, together with his wife, according to a Florida sheriff's department.
The phrase "out of the frying pan, and into the fire" immediately comes to mind.
