MIAMI (AP) — A Florida couple accused of kidnapping their two young sons and fleeing by boat to Cuba were handed over to the United States and imprisoned and their children were returned to their maternal grandparents, who have official custody, authorities said Wednesday. Joshua Michael Hakken and his wife, Sharyn, were being held at the Hillsborough County Jail on a number of charges including kidnapping, child neglect and interference with custody, the Hillsborough County Sheriff's Office said on its website. The TBI had issued an Amber Alert for the boys last week when the family was reportedly spotted in Tennessee, but that was a mididentification.
