(CHICAGO, ILLINOIS) A federal grand jury has indicted Marimar Martinez, a 30-year-old Chicago resident and U.S. citizen, after an October 4, 2025 confrontation in Brighton Park that ended with a Border Patrol agent shooting her multiple times. Martinez is charged with forcibly assaulting, impeding, and interfering with a federal law enforcement officer. Prosecutors say the charge carries a potential penalty of up to 20 years in prison.
The shooting, which federal officials say unfolded during the Trump administration’s “Operation Midway Blitz,” has become a flashpoint in the city’s debate over immigration enforcement operations and the use of force by federal agents.

Allegations and sequence of events
- Authorities allege Martinez and another Chicago resident, 21-year-old Anthony Ian Santos Ruiz, used their vehicles to follow and strike a silver Chevrolet Tahoe driven by Customs and Border Patrol personnel acting as a security detail in Oak Lawn.
- According to the complaint, the two followed the agents’ vehicle for 20 to 30 minutes before the encounter moved to 39th Place and Kedzie.
- Federal officials say Martinez’s SUV sideswiped the Border Patrol vehicle and that Martinez and Ruiz “boxed in” the agents, prompting one agent to fire at Martinez. Prosecutors count five shots; Martinez’s attorney says she was struck more times.
The government’s early account also stated Martinez “attempted to run over agents and was armed with a semi-automatic weapon.” Yet Martinez holds a valid concealed carry license, and police audio reportedly confirms her legally owned gun remained inside her purse during the incident, according to her defense lawyer. The clash between those narratives—one from federal agencies, one from defense counsel—sits at the center of a case with sharp stakes for Martinez and broader questions for Chicago’s immigrant communities living amid stepped-up federal operations.
Conflicting evidence and attorney’s claims
Evidence gaps are driving much of the dispute. Only three Border Patrol body cameras were activated during the shooting, despite several agents on scene. Nearby security footage from a tire shop shows a white Chevy Tahoe followed closely by Martinez’s silver Nissan Rogue and Ruiz’s black GMC Envoy, but the video did not capture the collision or the moment shots were fired. That partial record leaves key facts in question.
Martinez’s attorney, Christopher Paree, makes several contested claims:
- He says body camera footage shows an agent holding an assault rifle moments before the shooting and saying, *“Do something, b**ch.”*
- He further claims the agent turned the federal vehicle into Martinez’s vehicle before exiting and shooting her seven times, a count that conflicts with the prosecution’s tally of five.
- Paree’s description directly challenges the federal claim that agents acted in self-defense. Federal prosecutors have not publicly addressed that specific allegation.
There are also disputes about location and witness accounts:
- Homeland Security initially said the encounter happened in Broadview, while court records place it in Brighton Park.
- Officials claimed agents were surrounded by “10 cars,” a point witnesses contest, saying agents were not boxed in.
These mismatches have fueled public concern over transparency, especially given the intensity of Operation Midway Blitz and the stakes when Border Patrol interacts with residents away from the border.
Legal proceedings, releases, and rewards
- Martinez has been released from custody pending trial after U.S. Magistrate Judge Heather McShain found she posed no flight risk.
- Her attorney says she is still recovering from her gunshot wounds and needs immediate medical care.
- Ruiz, charged with the same federal offenses, was also released and will appear in court at a later date.
- The FBI and ATF have announced a reward of up to $50,000 for information leading to arrests and convictions connected to the alleged ramming incident.
Broader context: Operation Midway Blitz and community impact
Federal authorities describe the October 4 operation as part of “Operation Midway Blitz,” attributed to the administration of President Trump. Community advocates and defense counsel say the operation has brought unusual federal activity to Chicago neighborhoods far from the border, increasing the risk of confrontations.
According to analysis by VisaVerge.com, the case sits within a broader pattern of encounters between federal immigration agents and Chicago-area residents during Operation Midway Blitz, including at least two shooting incidents since September 2025.
Key unanswered questions remain central to both the criminal case and the public debate:
- Did Martinez and Ruiz ram or box in a federal vehicle, as authorities claim?
- Or did agents escalate the situation, as the defense says, by turning into Martinez’s car and firing without a clear threat?
With only a partial video record and differing counts of shots fired, the outcome may hinge on technical evidence and testimony under oath.
Community concerns and official responses
For families in Chicago’s mixed-status communities, the case lands amid fear that immigration operations can spill into daily routines—commutes, school runs, and ordinary errands. Even U.S. citizens like Martinez, her defenders argue, can be pulled into high-stress encounters when Border Patrol teams operate in urban neighborhoods.
- If the federal narrative stands, prosecutors will argue that agents responded to an immediate threat.
- If the defense account persuades a jury, the case could raise profound questions about federal tactics in cities.
Officials have offered limited comment beyond the charging documents and early statements about the chase and alleged ramming. The government maintains that Martinez and Ruiz pursued the agents for 20 to 30 minutes, struck the Tahoe, and created a dangerous box-in that forced the agent to fire. The defense, pointing to the concealed carry license and the claim that the firearm stayed in Martinez’s purse, says the government’s early statements painted a false picture of an armed suspect who tried to run over agents.
Community leaders emphasize the need for full video records whenever agents use force. While only three body cameras were active here, the public will likely focus on their footage in the weeks ahead.

What’s next
- Prosecutors must prove that Martinez forcibly assaulted or impeded a federal officer to secure a conviction.
- The defense will aim to show she posed no immediate threat and that agents escalated the encounter.
- The charge’s 20-year maximum highlights how seriously the federal government views interference with on-duty officers, especially in the context of an ongoing operation.
For now, Martinez remains under court supervision, recovering from her injuries and awaiting the next hearing. Ruiz faces the same path. The reward from the FBI and ATF remains active, signaling the government’s resolve to pursue evidence about the alleged ramming.
The Brighton Park neighborhood—named in court papers, despite an early government reference to Broadview—remains the physical marker of a case that will likely shape how Chicagoans see Operation Midway Blitz and Border Patrol presence on their streets. Whichever account prevails, the trial will carry lasting effects for Martinez and Ruiz, for agents assigned to urban operations, and for residents who want clear rules when federal immigration teams operate in their city.
