Sources with the Bureau of Alcohol, Tobacco and firearms told News4 it is likely a Colt AR15, much like this M-16, or a Ruger Mini 14.

Does anyone know if these all use the same ammo?

Yes, in an out-of-the-box condition, all three would use .223 Remington, the American civilian loading equivalent to the 5.56mm NATO.
