ABC News sources tell the outlet that authorities are investigating whether Border Patrol agent Nicholas Ivie was killed earlier this week as a result of friendly fire.
Ivie was shot and killed while on horseback in the wee hours of Tuesday morning near the border of Naco, AZ.
The scenario that is being examined is whether the fatal shooting happened in the “fog of war” following some type of encounter.
Additional forensics are being done on ballistics and additional interviews are being conducted to determine if the matter can be resolved in the coming days.
It's unclear from the report if this possibility is a normal part of any investigation or if it is considered a strong possibility that warrants a more in-depth look.
Ivie was shot along with another colleague who was taken to the hospital but survived. They were ironically assigned to the Brian Terry station, named after a slain agent killed with a gun from Fast and Furious.
