The Vanderburgh County Sheriffs Department is cracking down on sex offenders not complying with the sex offender registry. There are about 400 convicted sex offenders in Vanderburgh County. Only 133 of them incarcerated. Keeping track of those not in jail is a never ending task for sheriff deputies, but one they take very seriously. The department filed 32 charges of registry violators last year, and have already made several arrests since the new year began This time of year they are trying to get everyone getting out of prison or recently convicted registered for 2008, so the remainder of the year can be spent monitoring these types of offenders. Laws like the Adam Walsh Act of 2006 are helping, creating a national database. Even local efforts like the recently passed county ordinance that charges offenders a fee for registering, that says Sheriff Eric Williams pays for staff to keep track of them. There are currently more than 600,000 registered sex offenders nationally, which keeps local law enforcement agencies busy working across state lines to find them.
