Jonathan Ross, the Immigration and Customs Enforcement officer identified by multiple news outlets as the federal agent who shot 37-year-old Renee Good in Minneapolis on Wednesday, is a veteran deportation officer in ICE’s Enforcement and Removal Operations division, according to sworn testimony from the federal district court in Minnesota obtained by WIRED. A member of a Special Response Team, ICE’s version of a SWAT team, he’s had duties as a firearms trainer and led teams drawn from multiple federal agencies including the FBI, Ross testified.

The testimony stems from a December 2025 trial related to a June incident with parallels to the interaction that led to Good’s killing.

In June according to Ross’s testimony, he led a team seeking to apprehend a man named Roberto Carlos Muñoz-Guatemala, who was on an administrative warrant for being in the United States without authorization. Because the man’s home was across from a school and immigration agents had no authority to enter his home, Ross testified, they instead trailed him in unmarked vehicles.

Muñoz-Guatemala’s attorney did not immediately reply to a request for comment.

According to the December testimony and a New York Times account of an FBI agent’s affidavit associated with the case, Ross approached Muñoz-Guatemala and asked him to roll down his window and open his door. Ross, who testified that he had been driving an unmarked vehicle, was dressed in ranger green and grey, and wore his badge on his belt, broke the driver’s side back window and reached into the vehicle, at which point Muñoz-Guatemala pulled away.

While being dragged at a speed he claimed seemed like “40 miles an hour at least, if not more,” Ross pulled out his Taser and fired it at the driver. Muñoz-Guatemala continued to drive, and succeeded in shaking Ross from the car. At trial, Ross testified that he suffered injuries that required 33 stitches.

According to the affidavit, Muñoz-Guatemala called 911 to report that he’d been assaulted by ICE, which led to his arrest. Last month, he was convicted of assault on a federal officer with a dangerous weapon.

Reports from the Minnesota Star-Tribune and The Guardian identified Ross as the shooter who killed Good, a mother and recent transplant to Minneapolis, during an immigration enforcement action in the city. Video of the incident appears to show a federal agent firing shots into Good’s vehicle as she attempted to leave the scene. The officer did not appear to have been struck by the vehicle, and Good appeared to be turning the wheel to avoid contact, video analysis by The New York Times and the Washington Post shows.

At Thursday’s White House press briefing, vice president JD Vance answered questions about the incident, and his responses included numerous identifying details about Ross, mainly relating to his interaction with Muñoz-Guatemala. “That very ICE officer nearly had his life ended, dragged by a car, six months ago, 33 stitches in his leg,” said Vance, “so you think maybe he is a little bit sensitive about somebody ramming him with an automobile?”

Department of Homeland Security secretary Kirsti Noem has repeatedly described Good’s actions as an intentional act of “domestic terrorism.” An FBI investigation into Good’s killing is ongoing.

DHS spokesperson Tricia McLaughlin told WIRED in a statement that the department is “not going to expose the name of this officer. He acted according to his training.” McLaughlin added that federal immigration agents “are under constant threat from violent agitators” because of “doxxing” and that the Minnesota Star Tribune, which first published Ross’ name, “should delete their story immediately.”According to Ross’ December testimony, he served in the Indiana National Guard and was deployed to Iraq from 2004 to 2005 as a machine gunner on a patrol truck, then joined Border Patrol in 2007 after finishing college, working near El Paso, Texas.
