You have to scroll down past quite a few ads:
“Before Abston's conviction for kidnapping Durand, he had already appeared in juvenile court numerous times for charges including theft, aggravated assault, aggravated assault with a weapon, and rape, according to the lawyer's testimony. His first appearance in the system dates back to 1995, when he was only 12 years old.”
"It is quite likely that I would have been killed had I not escaped," victim Kemper Durand testified.

My guess is that he was tried as an adult for the kidnapping, and that Tennessee law allows for prior serious crimes to be brought up during sentencing.
