A man accused of kidnapping his two young sons in Florida and fleeing with them by boat was seen in Cuba Tuesday, accompanied by his wife and children..

Joshua Hakken is accused of breaking into his mother-in-law's home in Florida Wednesday, tying her up with zip-ties and fleeing with his sons.

The Tampa Bay Times reported that Hakken and his wife had lost custody of the children.

Investigators said the family left from a dock in Florida, aboard the "Salty," their recently purchased sailboat.

The newspaper said the boys' maternal grandmother was granted custody of the children after the Hakkens attended an "anti-government" rally in June in Louisiana, where police said they found him in a hotel room with a gun, marijuana and knife, talking about a "journey to Armageddon."

Hakken was charged with marijuana possession and the boys were placed in a foster home, where Hakken later showed up armed with a gun, the Times quoted authorities as saying
