E-mail alerts track sex offenders

People can now get "sex offender movement alerts" sent to their e-mail, cell phones and other Internet-enabled devices when sex offenders update their addresses with authorities in three states. Houston-based SCAN USA, which already provides information about weather, natural disasters and Amber Alerts, began the sex offender alerts Tuesday in California, Texas and Florida, with plans to expand it nationwide.
