 The unidentified male initially retreated after one of the troopers ordered him to step back. However, when the troopers exited their vehicle, the man charged at them while still brandishing the harpoon and ignored their commands to stop. That's when one of the troopers discharged their firearm, striking the man. Despite life-saving efforts by troopers and EMS, the assailant was declared dead at the scene. The Alaska State Troopers take all homicide investigations very seriously. We investigate officer-involved shootings the same way we investigate any homicide that occurs anywhere in the state of Alaska.
