On July 29, 2015, at around 9:16 a.m., a sergeant with the Arizona State Troopers observed a man attempting to push a white passenger car through the dirt median of Interstate 10 at milepost 191. The sergeant was already initiating a traffic stop as part of a commercial-vehicle-inspection detail in the area and was unable to check on the welfare of the man.
The sergeant radioed for another trooper to check on the man and a 13-year agency veteran trooper responded to the call.
After arriving on scene, the responding trooper immediately observed suspicious behavior from the man. Soon after, the man then physically attacked the trooper. A citizen observed the attack and stopped to assist the trooper.
During this time the man grabbed the trooper’s firearm, pulled it out of the holster and fired one round that did not strike anyone on scene. Two other troopers arrived and deployed a TASER in order to subdue the combative man. The citizen continued to help the trooper until the man was taken into custody.
The preliminary investigation discovered that the passenger car was reported stolen.
The trooper sustained an injury to his hand and was taken to Banner Casa Grande Medical Center and was released a short while later.
The combative man was identified as 26-year-old Colin Corkhill. He sustained injuries to his face. Corkhill was also transported to Banner Casa Grande Medical Center and released a short while later.
Corkhill was booked into the county jail located in Florence, Ariz., for two counts of aggravated assault and theft of means of transportation.
