The Investigations Division is supervised by a Detective Commander and is made up of 6 Investigators, 2 School Resource Officers, 1 Narcotics Officer assigned to the Drug Enforcement Administration (DEA), 1 Crime Analysis Assistant, and an Evidence Custodian. Elmhurst Detectives are trained, experienced investigators who specialize in crimes such as burglary, robbery, assault/battery, auto theft, identity theft, and document crime in addition to investigating deaths in the community. During the course of an investigation, detectives might be called upon to interview witnesses and victims, interrogate suspects, offenders, and/or examine crime scenes for physical evidence with which to identify suspects.
Investigators are assigned to follow up on crimes that were initially reported to the uniformed patrol division. Detectives are subject to call-in 24 hours/day, 7 days/week, and members of the division are also sometimes called upon to work with other local, state, or federal agencies to assist in more serious or complex cases.
In 2018, there were 231 cases assigned for investigation.
