Operation Guardian, a three-year national initiative specifically targeting the country's most dangerous noncompliant sex offenders, ended Tuesday with the arrest of 345 people who failed to register with state authorities as required by law, the U.S. Marshals Service said.

Details began emerging Tuesday about the horrors endured by three Cleveland women who were kidnapped and held for a decade in a run-down house with plastic bags over the windows, but researchers on abductions and sexual assault say there will be a lot of help for them and their families.

The Jerry Sandusky sex-abuse scandal at Penn State has galvanized leaders of youth sports organizations to come together to learn how to ensure such abuse doesn't happen in their ranks.
The women, who reached freedom Monday night, "are now embarking on their next journey, and that's the journey to heal," said John Ryan, chief executive of the National Center for Missing and Exploited Children, which supported the hunt for two of the missing women, Amanda Berry and Georgina DeJesus, who vanished as teens.
