Minneapolis live updates: DOJ launches investigation into Pretti killing, Deputy AG Blanche says

More information is emerging about Alex Pretti, the man who was shot and killed by federal agents in Minneapolis.

The 37-year-old worked for the Minneapolis VA Health Care System as an ICU nurse, according to AFGE Professional Local 3669, which represents professional employees affiliated with the Minneapolis VA Health Care System.

"(A) member of our union lost their life today, and that alone is devastating. Our hearts are heavy, and we are deeply stricken by this tragedy that has befallen one of our own," the union said.

The Department of Homeland Security alleged that Pretti approached border patrol agents with a 9mm semi-automatic handgun, and "violently resisted" when agents tried to disarm him. Local officials disputed that characterization.

Border Patrol commander Greg Bovino declined to give more details about the confrontation, claiming, "This situation is evolving. The investigation is ongoing. Those facts will come to light."

Minnesota Gov. Tim Walz and Minneapolis Mayor Jacob Frey, however, questioned the claims and admonished the federal government for a rush to judgment without spending more time gathering evidence.

Multiple videos of the confrontation showed federal agents spraying Pretti with a substance and pinning him to the ground before the shooting.

Minneapolis Police Chief Brian O'Hara said that Pretti was a legal gun owner and did not have a criminal record.

Minnesota's gun laws permit open carrying a handgun as long as the gun owner has a valid permit.

A judge in Minnesota has granted the temporary restraining order sought by local officials preventing Trump administration officials from destroying any evidence related to Saturday's fatal shooting.

"Defendants, together with their employees, agents, and anyone acting in concert with them, are ENJOINED from destroying or altering evidence related to the fatal shooting involving federal officers that took place in or around 26th Street and Nicollet Avenue in Minneapolis on January 24, 2026, including but not limited to evidence that Defendants and those working on their behalf removed from the scene and/or evidence that Defendants have taken into their exclusive custody," Judge Eric C. Tostrud ordered.

A hearing has been set for Monday.

In new court filings Saturday night, city attorneys for Minneapolis and St. Paul are painting a picture of the chaotic moments that ensued after the fatal shooting of Alex Pretti and are asking a judge to take immediate action to temporarily restrain federal agents' tactics and to declare the deployment of thousands of federal immigration agents unlawful.

In a sworn declaration, Minneapolis Assistant City Attorney Heather Robertson said federal agents initially asked Minneapolis police officers to leave the scene after the shooting, "but MPD stayed to hold the crime scene." Robertson said an MPD officer rode in the ambulance with Alex Pretti and that as Border Patrol and ICE agents began to line up wearing riot gear, at least one 911 caller requested assurance that Minneapolis police officers were on the scene.

She also said that in the minutes after the shooting, "Minneapolis 911 callers also reported that ICE agents were attempting to detain 30 bystanders."

City officials for both Minneapolis and St. Paul submitted a letter to the court asking Judge Katherine Menendez to reconsider her decision to convert a request for a temporary restraining order into a motion for preliminary injunction and to take immediate action.

"We need the Court to act to stop this Surge before yet another resident dies because of Operation Metro Surge," wrote the solicitor general, the Minneapolis city attorney, and the St. Paul city attorney.
