Defense attorneys for a Minnesota man convicted in December of assaulting Immigration and Customs Enforcement officer Jonathan Ross are seeking access to investigative files related to the killing of Renee Nicole Good, after learning Ross was the same officer who shot and killed her during a targeted operation in Minneapolis last month.

Attorneys for Roberto Carlos Muñoz-Guatemala asked a federal judge on Friday to order prosecutors to turn over training records as well as investigative files related to Ross, the ICE agent who killed Good on January 7 during Operation Metro Surge and was also injured in a June 2025 incident in which Muñoz-Guatemala dragged him with his car.

A separate post-trial motion by the defense, filed in the US District Court in Minnesota, asks the judge to pause deadlines for a new-trial motion until the discovery motion is resolved.

Muñoz-Guatemala’s attorneys argue that even if the court ultimately decides that any newly discovered evidence doesn’t entitle their client to a new trial, he’s entitled to explore whether there are mitigating factors that could impact the length of his sentence, such as whether Ross’ injuries could have been, to some degree, brought upon him by his own behavior.

A jury convicted Muñoz-Guatemala on December 10 of assault on a federal officer with a dangerous weapon and causing bodily injury.

Court filings say that Ross and other agents were attempting to interview Muñoz-Guatemala last summer, and possibly process him for deportation, because he had an administrative warrant out for being in the country without authorization. They surrounded his Nissan Altima and attempted to remove him from the vehicle. Ross then used a tool to shatter the rear driver’s side window before reaching inside. When the defendant accelerated away, Ross testified, he was dragged approximately 100 yards, during which time he repeatedly deployed a taser. Muñoz-Guatemala subsequently called 911 to report he’d been the victim of an assault.
