TAMPA, Fla. -

The Florida parents charged with kidnapping their boys after losing custody and fleeing to Cuba by sailboat have been ordered to remain in jail without bond.

Joshua and Sharyn Hakken made their first appearance before a Tampa judge on Thursday morning. They'll face a judge during a pretrial detention hearing on Monday on charges of kidnapping, child neglect, false imprisonment, burglary and interference with custody.

4-year-old Cole and 2-year-old Chase are now with their maternal grandparents, who have legal custody. The children were taken from them last week. They planned to talk about the ordeal publicly later Thursday morning.

Joshua and Sharyn Hakken arrived with their sons in Florida early Wednesday, accompanied by federal, state and local authorities after being handed over by Cuban officials.
