According to Frederick County Commonwealth's Attorney Glenn Williamson, on October 12th (2009 or 2010 we don't know) Jocelynn Mackenzie Carter filed a complaint that she was raped by a Front Royal police officer. She claimed that the officer pulled her over on the 24th of April in 2009, made her get out of the car and then took her to an undisclosed location and raped her.
Comment: She waited either 6 months or a year-and-one-half before she filed the claim. Either way, the officer, J. Lethcoe (assuming the incident was not recorded), would have had no way to prove at that point that he didn't rape her. The passage of time would have eliminated his ability to mount an alibi. As we have seen here many times, without any kind of recording of the officer pulling her over, how would it be possible for him to defend against this?
After a month long investigation in which the officer gave DNA samples and took, and passed, a lie detector test, it was determined that the allegation was false. Carter had alleged that Lethcoe was in uniform driving his official vehicle at the time. Based on this, I would assume there was videotape evidence which showed that the incident never took place.
On July 19th, Carter pleaded guilty to the charge of filing a false police report, and was sentenced to a year in jail, with four months suspended, was ordered to pay a $1,000 fine, and to serve two years unsupervised probation.
The second link below states that Carter told investigators that she told a friend about the rape, but the friend has denied that any such conversation ever took place. She also stated that the officer could be the father of her child, conceived around the time of the reported incident, but the DNA taken ruled out the officer as the father.
