Federal records have identified two Customs and Border Protection officials as the agents who opened fire on Minneapolis protester Alex Pretti during a chaotic street encounter that left the 37-year-old ICU nurse dead and sparked nationwide outrage.

According to ProPublica, internal documents shared with select members of Congress, Border Patrol agent Jesus “Jesse” Ochoa, 43, and CBP officer Raymundo Gutierrez, 35, discharged their pistols during a Jan. 24 operation in a busy food and arts district.

The two men were reportedly a part of “Operation Metro Surge,” an immigration enforcement effort that sent heavily armed, masked federal agents into Minneapolis and other cities. Both men are from South Texas and have been placed on administrative leave, a Department of Homeland Security spokesperson told lawmakers.

Pretti, who worked at a Department of Veterans Affairs hospital, was protesting the federal presence when the confrontation broke out. Bystander videos show him filming agents as they force a woman to the ground, then stepping between her and an officer before being pepper-sprayed, tackled, and pinned. As onlookers scream, agents fire around 10 shots.

Federal reports say one agent yelled “He’s got a gun!” before the shooting, and authorities later said Pretti was carrying a legally owned handgun. But some video appears to show an agent removing a gun from his hip before shots are fired, raising questions about whether he still posed a threat.

Until recently, local officials were kept in the dark about the agents’ names and key evidence, including body-camera footage, even as protests spread in sub-freezing temperatures across Minneapolis and other cities.

“We must have a transparent, independent investigation into the Minnesota shooting, and those responsible—no matter their title—must be held accountable,” said Republican Sen. John Curtis on X.

Lawmakers and civil rights advocates argue that the secrecy and use of masks have made it nearly impossible to hold officers accountable.

"In America, no one, no badge, no agency, no administration should operate behind a mask when they are detaining our neighbors," Missouri Representative Ray Reed said to local news. Reed is one of many lawmakers around the country who’ve introduced bills to keep ICE agents unmasked.

A Justice Department civil rights investigation is now underway, while members of Congress question how a protester trying to help someone off the pavement ended up dead in a hail of federal bullets.
