WALLACE, Idaho -

The Shoshone County Prosecuting Attorney has determined the deadly officer-involved shooting of a Montana near the Idaho-Montana border this last summer was justified.

Alexander Mandarino of Whitefish, Mont. was shot and killed by an Idaho State Police Trooper Todd McDevitt during a welfare check involving McDevitt and Shoshone County Deputy Adam Durflinger on June 12 at a turnout near Lookout Pass.

The officers questioned him for approximately 45 minutes as to why he wouldn't explain why he was driving his roommate's car with license plates for a vehicle owned by Mandarino. Mandarino then went to the passenger side of the car and grabbed a gun.

As Durflinger struggled to take the weapon from him, McDevitt shot him in the chest.

Shoshone County Prosecuting Attorney Keisha Oxendine said Tuesday that McDevitt and Durflinger were threatened with deadly force by Mandarino, he refused to obey McDevitt's commands and struggled with Durflinger, and so McDevitt's use of deadly force against him was justified.
