Officials confirmed on Wednesday that live bullets, including the round it is believed killed cinematographer Halyna Hutchins and injured director Joel Souza, were found on the set of the movie Rust last week after actor Alec Baldwin fired a gun during a rehearsal.

It also emerged that the .45-caliber Colt - which has been described by law enforcement as a legit" antique gun, not a prop gun - was not thoroughly checked before being given to Baldwin, who fired the lead bullet, according to officials and a new court filing.
