The Criminal Investigations Division is overseen by the investigations captain and comprised of a sergeant, associated detectives, and an administrative assistant.
The Butler County Sheriff's Criminal Investigations Division works closely with victims, witnesses, citizens, local agencies, state agencies, and federal agencies.
The division is responsible for investigating a wide range of crimes in Butler County as well as assisting other agencies in the region. This includes crimes against persons (i.e., homicides, suicides, sex crimes, and crimes against children) as well as property crimes (i.e., burglaries, auto thefts, financial crimes, and computer crimes).
Detectives are also active in assisting the Patrol Division with the investigations of fatality motor vehicle accidents, processing of crime scenes, and interviewing victims, witnesses, and suspects. Most of the detectives are assigned to general investigations and one detective is charged with primarily handling investigations within the Butler County Detention Facility.
The detectives of the Criminal Investigations Division have all received training in crime scene processing, photographing crime scenes and evidence, interviewing victims, interrogating suspects, and testifying in court. Detectives have also received specialized training in areas such as homicide investigations, child victim cases, motor vehicle accident reconstructions, and processing of methamphetamine labs - to name a few. They are responsible for processing their own crime scenes, no matter how large or small, and are responsible for submitting collected evidence to different agencies and laboratories for analysis.
