Tennessee prosecutors have dropped charges against a Georgia man accused of kidnapping and raping a woman in a Smoky Mountain cabin before a pizza deliveryman called police.

Assistant District Attorney Steven Hawkins told The Associated Press on Thursday that the credibility of the alleged victim was in doubt. He said that based on all the evidence, prosecutors believed they could not obtain a conviction against 46-year-old David Jansen of Snellville, Ga.

The 24-year-old Atlanta woman has twice pleaded guilty in separate cases in Georgia to making false reports about being assaulted.

Deputies arrested Jansen at the rental cabin in May after the deliveryman called authorities to say a woman was tied up in the cabin and had mouthed the words, "Please call 911."
