Amanda Berry
Now 27, was last seen at 7.40pm on April 21, 2003, the day before her 17th birthday, when she left the Burger King where she worked. The fast food restaurant at West 110th Street was just a few blocks from her home and about four miles from where she was eventually found.
A week after she disappeared, Ms Berry's mother received a call from a man, who was using her daughter's cell phone. The man said that her daughter was safe and that he had married her, according to the Charley Project, which has profiled more than 9,000 cold cases of missing people.

Georgina "Gina" DeJesus
Now 23, went missing on April 2, 2004 as she walked home from Wilbur Wright Middle School, where she took special education classes as a 14-year-old seventh grader. Ms DeJesus was last seen at a phone booth between 2.45pm and 3pm at the corner of 105th Street and Lorain Avenue, about five kilometres from the house where she was found.
Police initially believed that Ms DeJesus had run away because she was grounded by her parents for two months after being caught smoking a cigarette, according to the Charley Project.
It said that in 2006, Cleveland police searched under a driveway after receiving a tip about her whereabouts.
Ms DeJesus and Ms Berry were featured several times in America's Most Wanted, a television show that linked their disappearances.
