New Mexico authorities said Wednesday they have recovered a lead projectile believed to have been fired from the gun used in the fatal movie-set shooting. Investigators discussed their initial findings in the shooting in which actor Alec Baldwin fired a gun, killing a cinematographer and wounding the director. Testing is being done to determine whether the lead projectile recovered from director Joel Souza’s shoulder was fired from the gun used by Baldwin. Santa Fe County Sheriff Adan Mendoza said it’s too early to comment on whether any charges will be filed. He also noted that 500 rounds of ammunition—a mix of blanks, dummy rounds, and live rounds—were found while searching the set. The sheriff would not comment on how the rounds got on set.
