It was last October that actor Alec Baldwin fired a prop gun unaware that it was loaded.

When the revolver was fired, the film "Rust" photographer Halyna Hutchins was killed and director Joel Souza was injured.

In December, Alec Baldwin appeared on television for the first time since the accident, telling journalist George Stephanopoulos that he did not pull the gun.

But according to the FBI's report, obtained by ABC News, tests have shown that the weapon in question could not have been accidentally fired.

With the cock of the revolver in a fully cocked position, "the weapon cannot have been fired without pulling the trigger," writes ABC.

Baldwin's lawyer writes that the "important report in the context" is the medical one that shows that the incident was a tragic accident, and that Baldwin believed that the prop weapon was not loaded and safe to use.
