An Immigration and Customs Enforcement agent named Jaupre Williams pushed an Evanston resident to the ground during a Sept. 20 detainment near Dodge Avenue and Howard Street, The Daily Northwestern reported Oct. 21.

The Daily identified Williams through a review of internal ICE personnel records and dozens of photos and videos. He is the second agent publicly named in the incident. Supervisory ICE agent Esteban Rivas was identified earlier this month through Evanston Police Department body camera footage.

The detainee, a U.S. citizen whose name has not been publicly released, was hospitalized at St. Francis Hospital with injuries to his head, neck and teeth, according to an EPD news release issued Sept. 20.

What security footage shows

EPD security camera footage shows Williams pushing the man against a federal vehicle and then to the ground, The Daily reported. Williams wore a black ski mask concealing his face.

In body camera footage obtained by The Daily, Rivas referred to Williams as "one of my officers." ICE personnel files reviewed by the newspaper list Rivas as Williams' supervisor as of late August. Rivas' badge identified his full title as supervisory detention and deportation officer, according to footage he showed Evanston police.

Williams had previously worked for the Federal Protective Service, the agency that provides security to federal buildings. A court document from an August 2025 incident in Los Angeles identified him as an inspector for that agency. He became an ICE agent by early November 2025, personnel files indicate.

The Daily confirmed Williams' identity in part by matching footage across several incidents. Video of a Sept. 25 arrest outside the Cook County Domestic Violence Courthouse in Chicago showed Williams driving the same dark blue Ford Explorer seen in Evanston and wearing a similar black smartwatch. A person familiar with Williams' activities on the West Coast, granted anonymity by The Daily for fear of retribution from federal officials, also independently identified him.

ICE declined to confirm the identities of either agent. An agency spokesperson told The Daily on Oct. 5 that ICE would "never confirm or deny attempts to dox our law enforcement officers."

The Sept. 20 incident

Federal agents detained the Evanston man in the morning near Dodge Avenue and Howard Street as part of what a Department of Homeland Security spokesperson called a "targeted enforcement operation," according to The Daily's initial coverage.

The agents said they were seeking someone with a federal warrant and believed the man resembled their target, according to an EPD news release. He was briefly detained and released after agents determined he was not the person they sought.

In 911 audio obtained by The Daily, a scuffle can be heard in which the man asks the agents to stop and tells them he is a U.S. citizen. Five federal agents were operating in the area in separate vehicles at the time, one agent told Evanston police.

Then-Evanston Mayor Daniel Biss wrote in an Instagram post that the man was treated for "minor injuries" at St. Francis Hospital. The city's police chief met with the man at the hospital, and an evidence technician photographed and documented his injuries, WTTW reported.

Investigation status

The EPD detective bureau was investigating the incident as of a Sept. 25 city manager's memo, reviewing video, interviewing witnesses and documenting injuries under case number 26-64880. No public update on the investigation's status has been reported since.

A spokesperson for activist group Sanctuary Evanston called the Sept. 20 incident a "violent assault" in a statement the following day.
