Two federal officers fired shots during the encounter that killed ICU nurse Alex Pretti in Minneapolis, a Customs and Border Protection official told Congress in a notice sent Tuesday.

Officers tried to take Pretti into custody and he resisted, leading to a struggle, according to a notification to Congress obtained by The Associated Press. During the struggle, a Border Patrol agent yelled, “He’s got a gun!” multiple times, the official said.

A Border Patrol officer and a CBP officer each fired Glock pistols, the notice said.
