An Internal Revenue Service agent was shot and killed Thursday during a routine training exercise in north Phoenix.

Charlotte M. Dennis, spokeswoman for the IRS field office in Phoenix, confirmed that special agents were participating in the exercise at a shooting range when the shooting occurred.

The officer, whose name has not been released, died shortly after arriving at HonorHealth Deer Valley Medical Center, Dennis said.

No other injuries were reported.

Dennis declined to elaborate.

The range is located on property owned by the Federal Bureau of Prisons. But because of an interagency agreement, other law enforcement agencies often use the facility.

Officials at the FBI’s Phoenix field office said they will oversee the investigation into the shooting. The results will be delivered to the US Attorney’s Office for the District of Arizona.
