Photos: Twenty Colorado sex offenders who failed to register

Big photos below.

The Colorado Bureau of Investigation maintains a website focused on convicted sex offenders in the state -- including those whose current whereabouts are unknown, because they've failed to register with authorities. We've collected photos and identifying information for twenty such creeps. If you recognize any of them, phone the CBI at 303-239-5732 -- and given that none of them are currently incarcerated, you just might. Check them out below.
