(CNN) -- Colombia is preparing to hand over to U.S. officials a Dallas teenager who was mistakenly deported after she ran away from home more than a year ago, the South American country's foreign ministry said in a statement Thursday night.





Jakadrien Turner will be turned over to diplomatic officials Friday so she can be transported to the United States, the statement said. But the foreign ministry did not say when -- or how -- that will happen.





The U.S. Embassy in Bogota is working with Colombian authorities but cannot provide additional details "due to privacy considerations," said a U.S. State Department official who asked to remain anonymous per department policy.





Jakadrien somehow wound up deported to Colombia after U.S. authorities mistook the girl, who lacked identification, for a Colombian national.





Family members said Thursday night that they were thrilled at the news that the 15-year-old would be returning home.





"It's a giant step. I'm relieved, but I won't be completely relieved until I get her in my arms again," the girl's mother, Johnisa Turner, said. "A weight has definitely been lifted."





Grandmother Lorene Turner said U.S. Embassy officials called with the news that her granddaughter would be turned over to U.S. officials.





"When I heard those words I didn't hear nothing else. I flipped out. I can't wait," she said.





But Jakadrien's family was still demanding to know why immigration authorities deported the teen -- a U.S. citizen with no knowledge of Spanish -- and why they simply took her at her word when she gave them a fake name.





The teen's family had been searching for her since she ran away in the fall of 2010. Her grandmother scoured Facebook looking for the girl, viewing Jakadrien's friends' pages for any information.





"There's no words," Johnisa Turner told CNN of the ordeal. "It hasn't been easy at all."





The Colombian Institute for Family Welfare confirmed Thursday that Turner is in its custody, is pregnant, and entered the country as an adult. The institute said Colombian authorities learned about the case a month ago.





After Jakadrien went missing, the family managed to track her to Houston, where she worked at a DJ club under a different name. They tried to get help from authorities there, to no avail.





Then, to the family's surprise, they learned their teenage daughter was in Colombia, partying with men and smoking marijuana. They later learned from a detective that Jakadrien was pregnant.





How Jakadrien got to Colombia is a mystery to the family. The Immigration and Customs Enforcement agency maintains she was arrested in Houston for theft and told them she was an adult from Colombia.





The agency says authorities believed her story because she maintained her false identity throughout the process. They handed her over to an immigration judge, who ordered her removed from the country.





"At no time during these criminal proceedings was her identity determined to be false," the agency says.





It says criminal database searches and biometric verification revealed no information to invalidate Jakadrien's claims.





The family's attorney, Ray Jackson, says it doesn't make sense.





"They dropped the ball," he said.





He says the immigration agency took Jakadrien's fingerprints but failed to match them to the name she gave. The name matched a woman wanted by Interpol, Jackson says, so they "shipped her on through."





The agency says it is taking the allegations very seriously and is "fully and immediately investigating the matter in order to expeditiously determine the facts of the case."





For months, family members said they frantically searched for signs of the missing teen.





Jakadrien had run away once before, two weeks earlier, her mother said, and Jakadrien told her the family didn't give her enough freedom. Her good grades at school had dropped off, something Turner blamed on the normal problems of teenagers. In addition, Jakadrien's grandfather, her mother's father, had recently died.
