Bill Would Require GPS For Some Sex Offenders

COLUMBUS, Ohio -- Tier 3 sex offenders could be monitored for life.

House Bill 538 would require tier 3 sex offenders to wear a GPS tracking device for the rest of their lives, once released from prison.

Earlier in 2008, sex offenders were broken into tiers -- as part of the Adam Walsh law.

Tier 1 offenders must register once a year, tier 2 offenders register every six months and tier 3 offenders register every 90 days.

A group of sex offenders is suing, claiming the law is unconstitutional because it reclassified 26,000 offenders without a new hearing.
