The attorneys representing the individuals said nearly a year after "Operation Midway Blitz," no charges have been filed against Immigration and Customs Enforcement agents. They said they hope the filings will lead to criminal prosecutions, including felony charges.
Among those filing reports was Marimar Martinez, who was shot five times by a Border Patrol agent.
"This man shot five bullets directly at me and tried to kill me. My car and body were pierced with bullets," Martinez said.
Martinez said she believes the federal government has failed to act against the agent involved.
"It has been 10 months since Charles Exum tried to kill me, and the federal government has failed to act or even discipline Charles Exum," she said.
Martinez was initially charged, but those charges were dropped.
The Department of Homeland Security said in a statement Monday, "On October 4, Border Patrol law enforcement officers were ambushed by rioters that hit federal agents with their vehicles."
DHS went on to say the Border Patrol agent who shot Martinez was placed on administrative leave. DHS said the Department of Justice would answer any further questions on the case.
Other individuals involved in the filings said that action does not go far enough.
"Those who violated me operate in the shadows, masked, nameless and shameless," Dayanne Figueroa said.
The nine police reports were filed in connection with "Operation Midway Blitz." Attorneys for the group said they want law enforcement and prosecutors to pursue criminal cases.
"Our hope today is either one, a police officer takes the step to charge these officers with a misdemeanor, or the Cook County State's Attorney's Office approves these charges for criminal prosecutions," said Brian Orozco of Kulis Law Ltd. and the Chicago Project.
Supporters of the filings pointed to findings released earlier this year by the Illinois Accountability Commission. In April, the commission released a special report that they said highlighted unconstitutional uses of force.
"We saw ICE officers ramming their cars into other people. We saw them chase folks through grocery stores, through other people's yards, for no apparent reason," said Jimmy Arce of the Illinois Accountability Commission.
Cook County Commissioner Jessica Vásquez said advocates will continue pressing for accountability.
"We are committed to do the work and to continue pushing for justice for all of our people," Vásquez said.
The Cook County State's Attorney's Office said in a statement that federal agents are not exempt from prosecution when evidence supports criminal charges.
"No one is above the law - including federal agents - and the CCSAO will not hesitate to prosecute any case when it is supported by the evidence and the law," the office said. "Under state law, law enforcement must investigate alleged criminal conduct before prosecutors can file charges."
The office added that it previously released a protocol to assist law enforcement agencies investigating incidents stemming from "Operation Midway Blitz," and said it remains committed to supporting those investigations, including an ongoing Illinois State Police investigation into the death of Silverio Villegas González.
ICE says every officer working in the field will have a body camera by the end of the month.
