She's always said that he shot her. Shyne just took the fall. Shyne has always maintained that he shot in the air, and he never thought those injured were because of him. There were different shells, guns and all of that. I'm trying to remember back then, but I believe they said ballistics ruled out Shyne as the one that injured them.
This is a situation where, someone is going down for this, so since Shyne was there and participated, it was on him. Puff's lawyers beat that. Plus, I think Shyne admitted shooting, while Puff never did so...
