Investigators are assigned cases which are felony level crimes.  The Criminal Investigation Division has responsibilities ranging beyond the investigation of felony crimes to include: Property and evidence room management, regulation of the Sex Offender Registry and investigation of registry violations, intelligence gathering and dissemination of critical information, and assisting the other divisions of the Sheriff's Office as directed.  Investigators work closely with many outside agencies, as most of the crimes investigated cross county lines.

If you have questions or concerns regarding a local sex offender, please call 563-264-0188 for Sergeant Jacob McCleary, ext. 4105, Detective Hailee Polito, ext. 4128 or Detective Adam Bell, ext. 4004.
