ST. CHARLES — Five registered sex offenders are jailed after a surprise roundup in St. Charles County.
Federal and local police worked together on the operation dubbed "Knock and Talk."
A federal grant allowed 21 officers to work over three days on the effort that authorities say uncovered 65 crimes and netted five arrests.
Police say most of the offenses were minor, including not letting authorities know about changes in e-mail addresses or cell phone numbers. But five computers were confiscated, including some suspected of containing child pornography.
