Here in Ohio, it's called "inducing panic" and it starts out as a first degree misdemeanor; however, if economic harm or physical harm results, it moves up to a felony charge.
If you are correct, it sounds to me like the 911 caller from the Beavercreek Walmart shooting needs to be tried for murder. In Ohio (and many other states), if a death results from your commission of a felony, you are guilty of murder.
