Sheriff says he doesn't "believe it was an "assault rifle"".
More info on the other incident that they think may be connected.
An Asian male walked in another dance hall with a weapon which was then wrested from him, he then fled in a white van. This occurred shortly after the above shooting. No word on what the weapon was. If true he may have been going for round 2 at another Lunar NY celebration.
Edit: He just said "it was not an assault rifle".
