The largest mass shooting in U.S. history might have been much worse, had the alleged assailant's gun not jammed, according to reports.
James Holmes was due to make his first court appearance Monday since allegedly killing 12 people and wounding dozens, nine critically, during a midnight screening on the opening night of "The Dark Knight Rises" Friday in the Denver suburb of Aurora, Colo.
Holmes is accused of entering the theatre with three guns, including a semi-automatic assault rifle with an extended magazine.
When that gun jammed, he was forced to use a pistol, potentially saving lives, the reports say.
There are also now indications Holmes may have gotten away that morning, if not for observant SWAT officers who noticed something off about his tactical gear.
"There was one particular piece of equipment that he had on him that was out of place, and I am so proud of my officers that they spotted that right away and challenged him," Aurora Police Chief Dan Oates said on the CBS News broadcast "Face the Nation" Sunday.
That piece of equipment was a non-regulation gas mask. Holmes was arrested at the scene.
Oates said there's no mistaking his intent.
