One person was critically injured Tuesday in Arivaca, Arizona, during a shooting involving U.S. Border Patrol after what an FBI spokesperson described as an “alleged assault on a federal officer.”
The incident occurred around 7:30 a.m. near milepost 15 of West Arivaca Road, located near the U.S.–Mexico border. Federal agents were trying to detain the man — identified as 34-year-old Patrick Gary Schlegel — when he opened fire at a Border Patrol helicopter, the FBI said, according to the Associated Press.
