Editor's note: Nancy Grace's new show on HLN, "Nancy Grace: America's Missing," is dedicated to finding 50 people in 50 days. As part of the effort, which relies heavily on audience participation, CNN.com's news blog This Just In will feature the stories of the missing.
This is the 30th case, and it will be shown Friday at 9 p.m. on HLN.
The morning of May 4, 2007, Kara Kopetsky decided to walk to school in Belton, Missouri, instead of having her mom drive her. Later that morning, she called her mom and asked her to bring a book for one of her classes that she had forgotten at home. She also asked her mom to wash her work clothes because she had to work after school. Her mother dropped off the book, and Kara retrieved it. But what happened next remains a mystery.
Kara did not come home from school and did not show up for work. The last call on her cell phone was about 10:30 a.m. Since then, police say, the cell phone has been shut off or the battery has run down. There has been no activity on her bank account, and nothing is missing from her house.
Someone reported seeing Kara on May 17 at a gas station in Louisburg, Kansas, with an unidentified man, but the sighting could not be confirmed because the video surveillance system was not working. Since then, the trail has run cold. An $80,000 reward has been offered for information leading to her whereabouts.
Watch Nancy Grace Monday through Sunday starting at 8 p.m. ET on HLN. For the latest from Nancy Grace click here.
