Authorities recover bullet believed to have been fired by Alec Baldwin from film director's shoulder

Authorities in New Mexico said Wednesday they have recovered a bullet believed to have been fired from the gun used by Alec Baldwin in last week's fatal shooting on the set of the movie "Rust." The announcement comes six days after the actor fired a gun that was thought to be safe while rehearsing a scene last Thursday on the set of the Western movie "Rust," killing cinematographer Halyna Hutchins and wounding director Joel Souza.

Santa Fe County Sheriff Adan Mendoza said a lead projectile, which police consider to be a bullet, was recovered from Souza's shoulder. He said investigators have collected approximately 600 pieces of evidence, including what investigators believe was the gun fired by Baldwin, as well as "possible additional live rounds on set." All of the recovered items will be sent to the FBI for analysis, Mendoza said. 

Mendoza said they recovered about 500 rounds of ammunition from the set, which is a mixture of blanks, dummy rounds and "what we are suspecting, live rounds." He said there were three firearms recovered on the set: the gun believed to be fired by Baldwin, a revolver that appears to have some kind of modification to the cylinder, and a plastic non-functioning revolver.
