Over the years, the Border Patrol has come under scrutiny for its agents' use of deadly force and the lack of transparency surrounding these incidents. This had led to there being no complete picture of how many have died in Border Patrol-related shootings or incidents in the last decades.
The Guardian tallied 97 instances of deadly force used by Customs and Border Protection officers — this includes Border Patrol agents and customs officers — in the last 15 years, 23 of them in Arizona. The Arizona Republic has counted 57 people killed by on-duty Border Patrol agents and custom officers since 2005; 20 of those were in the agency's Tucson and Yuma sectors.
There are dozens of others where the person or agent was wounded but survived.
A search through the Arizona Daily Star archives since the 1990s, along with government watchdog group reports, paint a picture of agents using their firearms in response to rock throwers or accidentally discharging their weapons. It also shows instances when agents fired in response to bandits robbing migrants or suspected drug smugglers shooting at them or trying to grab their service weapons.
Two agents have also been shot and killed by drug smugglers or bandits in the last 20 years: Alexander Kirpnick in 1998, and Brian A. Terry in 2010. In 2012, agent Nicholas Ivie was killed by friendly fire when agents responded to a sensor that had been triggered.
Here are some of the fatal shootings in Arizona from the Star archives:
