The Peoria County Sheriff’s Office Investigative Division is tasked primarily with the investigation of Felony offenses such as Burglaries, Violent Offenses, Sexual Assaults, offenses against children, as well as investigations that require specialized training.
The Peoria County Sheriff’s Office Investigative Division (S.I.D) is a multi-task-oriented unit of highly trained and experienced criminal investigators. The Division is led by Lieutenant Dan Corpus.
Within the Investigative Division, deputies receive specialized training to provide complete and fair investigations in to serious offenses. It is the goal of the Investigative Division to conduct investigations that strive for excellence and professionalism; and to provide compassion and understanding while diligently working for the citizens in their time of need.
In most cases, a citizen files an initial complaint with the Patrol Division. After the initial investigation has been completed by the Patrol Division, the case is referred to the Investigative Division, where it is then assigned to a detective for continued investigation and/or follow-up.
The Investigative Division oftentimes works in cooperation with other agencies, both within the county and outside the county, in efforts to solve crimes. Many times, offenders who are committing offenses within Peoria County are also committing other crimes in neighboring jurisdictions. Through cooperation and mutual intelligence sharing with the surrounding law enforcement agencies, the Investigative Division is often able to solve crimes when the offender is not a resident of this county.
Peoria County Sheriff’s Office Investigators also take pride in a strong working relationship with the Peoria County States Attorney’s Office. Investigators go to great lengths to provide complete and thorough investigations to the States Attorney’s Office for prosecution, and to assist the States Attorney’s Office until all aspects of the investigation have been resolved.
