Yeah, evidently, Heldreth was able to evade the Sex Offender registry by moving to North Carolina.
I think what happened is that they never updated the database. If Heldreth had absconded he would be in jail right now.
FDLE lost track of something like 18,000 sex offenders. I ran into a guy with a gps while I was at the grocery one day and he was not on the offender website.
There is an offender that is listed as living across the street from a friend of mine and she said he hasn't been living there in months. Either he absconded or they haven't updated his info in the database. So far we haven't received an answer to that question.
Oh, he's on the Florida sex offender registry, noted as having been convicted with two counts of rape of a minor (gender not specified) in Ohio. His Florida sex offender registration flyer can be seen here.
