The American Federation of Government Employees (AFGE) has confirmed the identity of the man shot and killed by a Border Patrol agent in Minneapolis on Saturday as Alex J. Pretti, one of its members.

Pretti, aged 37 and a resident of Minneapolis, was involved in an early morning immigration enforcement operation on Saturday. The operation was aimed at apprehending Jose Huerta-Chuma, an undocumented immigrant with a criminal background that includes domestic assault, disorderly conduct, and driving without a valid license.

According to officials, Pretti confronted the Border Patrol agents while wielding a 9mm pistol and “violently resisted” when they tried to take the weapon from him.

Medical personnel on-site provided immediate assistance, but Pretti was declared dead at the scene.

“At this time, many of the details remain unclear,” AFGE wrote in a statement. “Video of the incident is circulating on social media, and the Department of Homeland Security has publicly stated that the victim was brandishing a weapon at officers. However, based on the video currently available, that claim is not clearly established.”

AFGE said they are not certain if the Border Patrol agent who opened fire was a member of AFGE.

“This is an unfolding and extremely serious matter,” AFGE leaders wrote in the statement. “Until we have verified facts, it is important that we refrain from speculation or drawing conclusions.

“What we do know is this: 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. Until more information becomes available, I urge everyone to remain calm and encourage peace and restraint in all communications and actions.”
