( CNN ) -- The two boys abducted by their parents and taken to Cuba were `` well cared for '' on their trip , their grandmother told reporters . The children , Chase and Cole , do n't know they were abducted , Patricia Hauser said . All they know is they were on an `` adventure , '' she said Thursday . The boys -- 2 and 4 -- appeared in front of reporters after Hauser spoke , smiling and showing off toys . `` We have not asked the boys anything about the journey . We are just letting them tell us as things come out if they feel like talking , '' said Hauser , who along with her husband was given legal custody of the children April 2 . Police say their father , Josh Hakken , broke into the home where the boys were living with their grandparents a day later , tying up their grandmother before whisking the two children away . Authorities say they traveled to Cuba on a sailboat . Authorities reunited the boys with Hauser and her husband on Wednesday after Cuban authorities turned the parents and the children over to U.S. officials . Boys reunite with grandparents . Hauser thanked U.S. State Department and Cuban officials for their work to find the children and bring them back to Florida . `` They called us from Cuba and let us talk to the boys before their plane even left , '' she said . `` Many tears were shed in that room from us . '' She said the family would not have any more news conferences or interviews , and asked that the media and public respect their privacy . `` We are trying very hard to shield the boys from media coverage , and we want them to get back to their normal everyday schedules and just be normal carefree boys again , '' she said . According to search warrant documents released Thursday by Florida authorities , Hauser told investigators that Hakken and his wife , Sharyn , had `` previously discussed suicide . '' The documents , citing the boys ' grandmother , also allege the boys ' father tied her to a filing cabinet with plastic cable ties before abducting the children `` with force . '' Thursday night , an attorney for the Hakkens agreed to the prosecution 's request that the Hakkens remain jailed without bond until trial . The next hearing is May 30 . The judge also appointed a public defender to represent the couple after they said they would n't be able to pay for a lawyer on their own . Later , the state attorney 's office filed formal charges against the Hakkens , including two counts of felony kidnapping . Given Florida sentencing guidelines , a conviction on the kidnapping charges could mean the Hakkens will spend the rest of their lives behind bars . Among the 11 counts , the couple was also charged with burglary , false imprisonment and child abuse . Police : Parents talked of 'journey to the Armageddon ' The circumstances leading up to the ordeal began in June when the family was staying at a hotel in Slidell , Louisiana . Responding to a call , police officers found the parents `` acting in a bizarre manner , '' Slidell police said in a statement . Inside the room where the boys were , authorities found narcotics and weapons . `` They were talking about 'completing their ultimate journey ' and were traveling across the country to 'take a journey to the Armageddon , ' '' police said about the parents . Louisiana authorities took the children from their parents after that incident . About two weeks later , the father showed up at a foster family home with a gun and demanded the return of the boys , Slidell police said . He fled after the foster parents called 911 . Over subsequent months , the parents `` did not participate in the system , '' said Sheriff David Gee of Hillsborough County . He did not offer details . `` As a result of that , the authorities in Louisiana gave custody to the grandparents , '' he said . That transfer became official on April 2 , when a Louisiana judge terminated the suspects ' parental rights . Early the next morning , Patricia Hauser told police , Josh Hakken entered her Florida home , tied her up and sped away with the children and the family dog in a silver 2009 Toyota Camry . They met up with Sharyn Hakken , sheriff 's investigators said , and eventually ended up on a 25-foot sailboat named Salty . The boat 's seller later tipped off authorities after word got out about the alleged abduction . It was at the Hemingway Marina just west of Havana , on Tuesday , that CNN found the family -- hunkered inside the boat , under the watch of Cuban security forces . That morning , U.S. officials in Havana told CNN that they were afraid the children could be in danger from their parents . Armed Cuban security agents watched over the family most of the day until the parents and children were led away peacefully that afternoon . Boys 'fine , happy and sleepy ' on return to U.S. Cuba and the United States are divided by far more than the Straits of Florida . But this week , U.S. officials repeatedly expressed their appreciation for the Cuban government 's `` extensive cooperation . '' The Cuban Foreign Ministry said the boat pulled into the marina in bad weather Sunday . The two governments shared information , which led to the return of the family and their dog to the United States . CNN 's Patrick Oppmann , Kim Segal and John Zarrella contributed to this report .
Note : The next hearing for the couple is set for May 30 . Josh and Sharyn Smith are accused of kidnapping the boys and taking them to Cuba . The boys thought they were on an island , their grandmother says . Police file several charges against the parents , including kidnapping and child abuse .
