The Type of Gun Used in the Louisville Bank Shooting

Two weeks ago, Morgan Chesky ran to the sound of gun fire inside a bank in Louisville. He is learning more about this employee that he had a master's degree in finance from the University of Alabama. We don't know exactly what type of weapon was used because the police didn't tell us. They didn't even say initially whether it was a rifle or a handgun. So police being very conservative about discussing the type of gun used in this crime.
