Tracking violent ex-cons: Registries grow, but do they work?

TOLEDO, Ohio (AP) — The slaying of an Ohio college student this summer is pushing state lawmakers to look at creating a public registry that tracks people convicted of violent crimes.

A review by The Associated Press finds at least seven states require some of their violent offenders to register after they’re out of prison. The lists are modeled after sex offender registries mandated by federal law.

The family of the University of Toledo student who went missing while bicycling began pushing for the idea after the arrest of a neighbor who was convicted of abducting another woman in 1990.

Experts who’ve studied criminal registries say the lists are popular, but research shows they don’t help protect people or reduce crime.

Backers say knowing where violent offenders live improves public awareness and safety.
