“It’s truly an honor to be appointed by Director Kelly to serve the men and women who make up the Division of Criminal Investigation,” said Lt. Colonel Trame. “I look forward to continuing our efforts to provide professional investigative services to our law enforcement partners in the service of the people of Illinois.”

This is the first change of command ceremony since Governor JB Pritzker reestablished DCI in 2019.

The history of criminal investigation within the ISP goes back over seven decades. In 1950, Governor Adlai E. Stevenson enacted an investigative arm of ISP dedicated to the suppression of gambling within the state. The unit grew and officers began working in plain clothes and conducting various criminal investigations, not only for ISP, but for local law enforcement as well, becoming the Criminal Investigation Bureau.

In 1977, Governor James R. Thompson reorganized ISP, known as the Department of Law Enforcement at that time, and combined the ISP Criminal Investigative Bureau with the Illinois Bureau of Investigation to create the Division of Criminal Investigation.

In 1993, Governor Jim Edgar combined the Division of State Troopers and the Division of Criminal Investigation into the Division of Operation, which existed until August 16, 2019, when Governor Pritzker reestablished DCI to support the delivery of professional and specialized criminal investigative service to the citizens of Illinois. This reestablishment incorporated many specialty units like Special Weapons and Tactics (SWAT) Teams, Medicaid Fraud investigations, Air Operations, criminal intelligence, and gaming enforcement. DCI Special Agents investigate crimes such as homicide, sexual assault, crimes against children, public integrity crimes, gun crimes, human trafficking, and illegal drug trafficking.

ISP thanks Colonel Cormier for his years of service to the people of Illinois and his great leadership within ISP. ISP welcomes incoming DCI Deputy Director Colonel Trame and we look forward to his leadership as ISP moves into its next 100 years.
