Harris County Sheriff's deputies are sorting through clues after three home invasion suspects were shot to death at trailer home. Sheriff Ed Gonzalez says the men were killed late this morning in Channelview after at least one homeowner opened fire with a shotgun. The sheriff believes one suspect was armed with a pistol but noted the information is preliminary. Gonzalez says reports of a fourth suspect appears to be untrue. The shooting is expected to be referred to a grand jury.
