Cops are asking for the public's help in finding two missing teens.

Kaylee Jones has been missing from her Georgia home for more than two months. Daniel and Brenda Jones fear their daughter has been sex trafficked. The 16-year-old, who is autistic, disappeared after the parents took away her phone. It had been discovered the girl has been chatting with several men online.

In a separate case out of Alabama, 17-year-old Tarasha Benjamin disappeared after going to a flea market. Benjamin left that Saturday morning with a friend. Then Benjamin borrowed the friend's car. It was found a mile from the flea market with the driver's side windows smashed. Benjamin has been missing since 2010.
