Accountability Commission refers federal agents for investigation, possible prosecution for conduct last fall

Chicago, IL (CAPITOL NEWS ILLINOIS) – A state board unanimously voted Thursday to approve a 204-page report detailing its investigations into misconduct by on-duty federal immigration agents amid Operation Midway Blitz.

It is also sending letters to local law enforcement agencies for potential prosecution of the agents. The letters are not determinations of guilt, but requests for further investigation by the relevant agencies. 

“Where that record establishes reasonable cause to believe that misconduct may have occurred, we implore those responsible to ensure that this information is reviewed and that it is handled in an appropriate fashion,” said Patricia Brown Holmes, vice chair of the body.

The Illinois Accountability Commission, created by Gov. JB Pritzker through executive order last October, was tasked with forming a public record to document the impact of the federal immigration campaign on Chicago communities, but also to produce recommendations for harm reduction and prevention of future abuses.

To inform its report, the commission conducted 16 investigations for which it interviewed over 60 people, reviewed nearly 100 hours of body camera footage from 250 videos, and reviewed hundreds of hours more of footage from security cameras, personal devices and social media, according to commission officials.

It also held seven private neighborhood listening sessions and five public hearings, featuring testimony from law enforcement experts, community advocates and everyday Chicagoans. 

“Documenting this was easy,” Commission Chair Rubén Castillo said. “The record is overwhelming; the video tapes are overwhelming. They’re devastating. They’re shameful. They’re brutal.”

Prosecution referrals

One of the referrals letters names Border Patrol agents Benito Nuñez, Carlos Chavira and Jesus Guillen, who the commission said used an intentional, high-speed car ramming maneuver in Chicago’s East Side neighborhood after being repeatedly instructed to stop by supervisors. 

Body camera footage released by the commission shows the agents proceeded to use teargas on a street of onlookers in the Far Southeast Side neighborhood, including more than a dozen Chicago police officers who had explicitly asked agents not to deploy the gas.

Others name Border Patrol agent Charles Exum, who shot Chicago teacher’s aide Marimar Martinez five times last October and then bragged about it over text, and Border Patrol agent Timothy Donahue, who made headlines for aggressive conduct in Evanston last Halloween.

In some cases, the commission was unable to identify specific agents involved. For example, a military-style raid on a South Shore apartment building references approximately 300 agents who may have broken agency policy or criminal law.

The commission says that’s due to its limited powers, which do not include the authority to issue subpoenas. That’s why it says law enforcement agencies should carry forward the cases, including the Cook County state’s attorney’s office.

“The issuance of this report is not the end, it is the beginning,” Castillo said. “We need a reckoning to occur.”

Commissioners said they hoped other states would follow Illinois’s lead, calling it an example for the nation.
