Border Patrol Agent’s Account Questioned in Chicago Teacher Shooting Case
New evidence released Wednesday challenges the Department of Homeland Security’s narrative surrounding the October 2023 shooting of Marimar Martinez, a 30-year-old Montessori school teacher who was shot five times by a Border Patrol agent in Chicago’s Brighton Park neighborhood.
Martinez and her attorney, Christopher Parente, unveiled text messages, surveillance photos, and body camera footage as they prepare to file a federal civil lawsuit against Agent Charles Exum and Department of Homeland Security officials. The evidence directly contradicts claims that Martinez “ambushed” agents and rammed them with her vehicle.
“I think Immigration and Customs Enforcement was hoping they would get some radical individual so they could support some of their false claims, but they picked the wrong victim to mess with,” Parente said during a news conference.
The newly released material includes congratulatory messages Exum received from colleagues after the shooting. “You are a legend among agents you better f—in know that,” one text read. “Beers on me when I see you at training.”
Parente alleges that evidence shows Exum lied to federal investigators when claiming he fired five shots through Martinez’s windshield as she drove directly at him. According to Parente, the government’s own evidence indicates one bullet hit the rear passenger window and another traveled from the rear of the vehicle to the front – contradicting Exum’s account of events.
Body camera footage from inside the agents’ SUV captures one agent saying “It’s time to get aggressive and get the f–k out” before another says “We’re going to make contact, we’re boxed in.” The recording then appears to show the SUV swerving left and making contact with Martinez’s vehicle before agents exit and five gunshots are heard.
Notably absent from the evidence is footage from Exum’s body camera, which was not activated during the shooting.
The attorney also disputed claims that agents were “boxed in” by showing surveillance footage that contradicts a diagram drawn by one agent depicting three vehicles blocking their SUV before the shooting.
Within hours of the incident, Border Patrol Chief Greg Bovino praised Exum in an email and offered to “extend your retirement beyond age 57” due to his “excellent service in Chicago.” In a separate text chain titled “Posse Chat,” Exum claimed he had received support from top officials including “Chief Bovino, Chief Banks, Sec. Noem and El Jefe himself,” apparently referencing Border Patrol Chief Michael Banks, DHS Secretary Kristi Noem, and possibly President Donald Trump.
Martinez survived the shooting and was initially charged with assaulting federal agents. However, prosecutors abruptly moved to dismiss the case with prejudice – meaning it cannot be refiled – just weeks later. Despite this, DHS website statements still describe Martinez as a “domestic terrorist” who “ambushed” agents.
In testimony before Congress last week, Martinez shared that she had been following a Border Patrol vehicle to warn others of their presence when the driver swerved into her car before they pulled over. When she tried to drive away, she felt a “burning sensation” in her arms and legs.
“I looked down and I noticed blood gushing out of my arms and legs,” she testified. “I saw my life flash before me and slowly began to think this was the end for me.”
A Border Patrol spokesperson confirmed Wednesday that Exum has been placed on administrative leave, adding that “CBP is committed to the highest standards of conduct, transparency, and accountability.” The spokesperson directed further questions to the Department of Justice.
Parente believes federal prosecutors in Indiana have launched a criminal investigation into Exum for the shooting, noting that Illinois prosecutors cannot handle the case since Exum served as their witness against Martinez.
The attorney connected this case to other recent fatal shootings by federal agents, including those of Renee Good and Alex Pretti in Minneapolis, suggesting a pattern of concerning behavior within the agency.
“All we’re doing is showing the American people that this agency — that is allegedly coming to all of our towns and will continue coming to all of our towns going forward as long as Trump remains in office — that they’re hiring people who have this mindset,” Parente said.

This case highlights the need for greater transparency and accountability in law enforcement, especially when it comes to use of force incidents. The new evidence seems to contradict the initial narrative provided by the Border Patrol agent. I hope the civil lawsuit can shed more light on the true circumstances surrounding this tragic shooting.
Agreed. The congratulatory messages from the agent’s colleagues are particularly concerning and suggest a troubling culture within the agency. Thorough investigations and independent oversight are crucial to ensuring justice in these types of cases.
This is a deeply troubling case that underscores the need for systemic reforms in how law enforcement interacts with minority communities. The new evidence suggesting a cover-up is extremely disturbing and must be thoroughly investigated. Restoring public trust will require a commitment to transparency and accountability.
I agree completely. Incidents like this erode confidence in the justice system and disproportionately impact vulnerable populations. A full, independent investigation is critical to uncover the truth and ensure appropriate consequences for any wrongdoing.
If the new evidence truly contradicts the agent’s account, then this is a very serious matter that warrants a full and impartial investigation. The use of force by law enforcement should always be a last resort, and any abuse or misconduct must be swiftly addressed.
Absolutely. The public deserves to have confidence that their law enforcement agencies are acting with integrity and professionalism. Hopefully this case will lead to much-needed reforms and greater accountability.
