The Department of Homeland Security (DHS) officially launched "Operation Midway Blitz" on September 8, 2025, describing it as a "focused effort to restore public safety and uphold federal law" by targeting "criminal illegal aliens" within the state of Illinois, which operates as a sanctuary state.

The operation's stated purpose was explicitly tied to a high-profile criminal case. The DHS announcement declared the mission was executed "in honor of Katie Abraham," a woman killed in a drunk driving hit-and-run car wreck caused by an undocumented immigrant, Julio Cucul-Bol, in Illinois. The DHS statement placed direct blame on Governor J.B. Pritzker's sanctuary policies, claiming they allowed "Tren de Aragua gang members, rapists, kidnappers, and drug traffickers" to "roam free on American streets," thus making Chicago a "magnet for criminals."

DHS Claims of Success and Criminal Examples

The DHS claimed significant success during the initial weeks of the operation. By October 1, 2025, the Department announced that U.S. Immigration and Customs Enforcement (ICE) and U.S. Border Patrol officers had arrested more than 800 individuals, later updating the figure to over 1,000 arrests by October 3, 2025.

The administration provided specific examples of the "worst of the worst" criminal illegal aliens reportedly arrested, including those with convictions or charges for:

• Murder (e.g., Aldo Salazar-Bahena)
• Aggravated Sexual Assault of a Child Family Member (e.g., Carlos Roman-Berrera, Bernardino Perez-Arrevillaga, convicted of aggravated sexual assault victim 13-17)
• Tren de Aragua Gang Affiliation (e.g., Ludwing Jeanpier Parra-Perez, a confirmed member; Carlos Johendy Gonzales Montero, a charged gang member)
• Domestic Battery/Violence, Felony Assault, and Sexual Assault (e.g., Jose Gonzalez-Ortiz, convicted of battery and arrested for sexual assault; Christian Alejandro Lopez-Cervantes, charged for felony assault, domestic violence)
• Multiple DUIs (e.g., Rosalio Pelayo-Salgado, arrested for eight DUIs)

The Department framed these arrests as direct evidence that sanctuary policies were jeopardizing public safety.

Detention Rate Contrast and Legal Challenges

While the DHS touted the more than 800 arrests as a major achievement, this official count must be considered in the context of the overall undocumented population in Illinois. With an estimated undocumented population of over 500,000 individuals in the state, the initial 800 arrests represent a documented detention rate of approximately 0.16% of the total undocumented population.

Furthermore, the operation has faced immediate legal and factual challenges:

• Warrantless Arrests: A federal judge ruled that ICE agents made at least 22 arrests without a warrant, violating the existing Castañon Nava consent decree, which limits warrantless arrests in the Chicago Area of Responsibility.
• Collateral Arrests: Civil rights groups and media reported instances of collateral arrests, including detentions of U.S. citizens without cause, and aggressive tactics like a South Shore apartment building raid utilizing a Black Hawk helicopter and heavily-armed agents.
• Fatal Incident: During the operation, an ICE agent shot and killed Silverio Villegas-Gonzalez in Franklin Park, Illinois, after he allegedly attempted to flee during an encounter while dropping his child off at school, leading to calls for an investigation.

The high-profile arrests cited by the DHS contrast sharply with the low overall detention rate compared to the total population, and the operation has drawn fire for alleged civil rights violations and the controversial use of force in a sanctuary jurisdiction.
