Investigators have the same requirements in law enforcement as the patrol deputies but primarily investigate felony level offenses. The Polk County Sheriff's Office Investigators are criminal Investigators that provide an important support function to the overall operation of the Sheriff's Office.


The Investigations Division in this office investigate primarily felony level offenses that include but are not limited to: 

  • Arson
  • Assault
  • Burglary
  • Child abuse/neglect
  • Fraud
  • Property crimes
  • Robbery
  • Sex crimes
  • Suspicious deaths
  • Theft

Complaint Sources

Some of these complaints are follow up investigations that originated with the patrol division of the office. Some are direct calls from the general public to the Investigators of the office. Others come in report form from other agencies (i.e. Social Services). Complaints/Crimes are primarily investigated through the interview and if relevant, interrogation, of victims, witnesses and suspects as well as the gathering and examination of various forms of evidence.
