What is the history of Hurst TX? -

My friends and i were digging and we found a piece of glass that looked as if it come from a saloon window. It was in the shape of a triangle but jagged around the sides. Nearby we found a rock that appeared to have blood on it. My friend thought that it might be a murder weapon. Can you help us figure this out?

Call 911, if it was a murder they would be the ones to figure it out.
