DES MOINES, Iowa — A deadly officer-involved shooting in Greene County on September 6^th has been ruled legally justified by the Iowa Attorney General’s Office.

The AG’s report said Officer Marshall Moore of the Boone Police Department attempted to pull Camryn Stonehocker, 18, of Boone, over around 10:24 p.m. after noticing a pickup truck with a taillight out while on patrol on Highway 30.

Stonehocker led law enforcement on a 20-mile chase that lasted about 17 minutes. During the pursuit, the AG’s report said he drove recklessly, at times driving at oncoming traffic in the opposite lane, driving down the middle of the road, and also abruptly stopping – forcing officers in pursuit to avoid colliding with his truck.

When he finally stopped just north of 220th Street on T Avenue, the report said Stonehocker exited the truck armed with a large survival knife and began walking toward Officer Moore. He ignored commands to drop the knife and continued pointing it at the officer while advancing.

Boone Police Officer Josh Olsen came up behind Stonehocker, which caused Stonehocker to turn, pointing his knife at the officer and coming toward him. Officer Olsen lunged out of the way, which sent him to the ground.

According to the AG report, Officer Moore saw Stonehocker turn the knife toward Officer Olsen and fired to prevent him from stabbing the officer. Stonehocker was hit by gunfire and fell to the ground and stopped moving. The knife was still clutched in one hand and once it was removed, Officer Olsen provided medical aid. During transport to the hospital, Stonehocker died from his injuries.

The officers involved in the incident were not injured.

The AG’s Office said interviews with Stonehocker’s friends and family showed he had been frustrated over previous encounters with law enforcement, and he’d received traffic citations two weeks before the fatal shooting.

They also recounted that Stonehocker had displayed more argumentative behavior over the last two years, coinciding with marijuana use. The report said he had been taking his mental health medication on a regular basis.

The Iowa Attorney General’s Office concluded, “that the law enforcement officers’ actions in this incident were legally justified and that criminal charges are unwarranted.”
