American Parents, Kidnapped Children in US Custody The American parents, who are accused of fleeing to Cuba from Florida with their kidnapped sons, returned to the United States early this morning in the custody of FBI agents. The airplane transporting Joshua Hakken, 35, his wife Sharyn Hakken, 34, from Cuba back to the U.S. landed at Tampa International Airport shortly before 3 a.m. ET, according to ABC News affiliate WFTS-TV. Their two young sons, Cole, 4, and Chase, 2, were also on the plane and returned to their grandparents. The Hakkens were booked at the Hillsborough County jail after their arrival. A few hours before the plane landed, authorities held a news conference and said both parents are facing kidnapping, child interference with child custody and neglect charges. In addition to those state charges, Joshua Hakken is facing grand theft auto, false imprisonment, battery and burglary. Hakken is also facing a federal charge for unlawful flight to avoid prosecution. The children's grandparents, Bob and Patricia Hauser, were also at the press conference, and said they had a phone conversation with their grandsons shortly before they departed for the U.S. Please continue to respect our privacy as we reunite with our precious grandchildren. Right now we're just looking forward to sitting and getting them in our arms and hugging them and being with them getting them home where they will be safe again," Bob Hauser said. Hillsborough County Sheriff David Gee said the kids appear fine. "Our understanding is that they're doing well and we're looking at them from a medical standpoint and all that will be checked out," Gee said. A team of FBI agents departed the Tampa area at 10 p.m. Tuesday and met with authorities in Cuba. FBI special agent David Couvertier said the U.S. State Department received information the family was in Cuba. Couvertier said they treated this kidnapping as a 'hostage situation' and did not consider it 'typical.' The Hakkens arrived in the Hemingway Marina in Havana on April 7 aboard their sailboat, Salty Paw, under unfavorable sailing conditions, according to a statement from the Cuban Foreign Ministry. The Hakken family was spotted by ABC News Tuesday getting off the boat in Havana and being escorted by government officials. After Joshua Hakken's boys were placed into protective custody last year, authorities said he showed up at their foster home banging on the door with a gun, demanding his two sons. The family dog, a terrier, was also found with the Hakkens in Cuba. Authorities say they have custody of the dog and it will be given to the boys once they land.
