Mackin v. State, 2016 UT 47 (Oct. 21, 2016)

After taking his ex-girlfriend’s purse, the defendant fled the scene.  His ex-girlfriend dove into his vehicle’s passenger window and climbed in while the defendant continued to drive.  The defendant was subsequently convicted of aggravated robbery based upon the use of the car as a deadly weapon.  On appeal, the Supreme Court held that a defendant may be convicted of aggravated robbery for using an object in a manner capable of causing serious bodily injury or death, even if the object is not ordinarily considered a weapon.
