U.S Border Patrol ( A man was killed on the Tohono O'odham Reservation by Border patrol )

A U.S. Border Patrol agent shot and killed a man Sunday in the Baboquivari Mountains on the Tohono O’odham Nation, federal officials confirmed today.
The incident occurred at about mid-day Sunday when an agent encountered a group who had crossed the border illegally, agency spokesman Victor Brabble said via email

A struggle occurred during the incident, leading to the agent shooting one member of the group.
Brabble did not say the nationality of the man who died.
The FBI is investigating, Special Agent in Charge James Turgal said this afternoon.
Sunday’s incident was the third fatal shooting by a Border Patrol agent in the Tucson Sector since Oct. 2. That day, agent Nicholas Ivie was killed in what FBI has determined was a case of friendly fire.
Eight days later, on Oct. 10, an agent in Nogales, Ariz. fired across the border and killed 16-year-old José Antonio Elena Rodríguez.
The FBI is investigating those cases as well. Mexican authorities are also investigating the killing of Elena Rodríguez.
