Crime Scene Investigators working for the Aurora Police Department found 76 spent rounds inside Theater 9 following the movie theater shooting on July 20, 2012.
During a long morning of testimony, Nick Carroll answered questions about dozens of crime scene photos and identified physical evidence as it was handed to him. The physical evidence included spent shells, live cartridges, gun magazines and even a pair of theater seats.
Carroll's testimony comes on day 11 of the trial of gunman James Holmes. He is accused of killing 12 people and injuring 70 others in the mass shooting at a midnight movie premiere. The prosecution is seeking the death penalty, while the defense has pleaded not guilty by reason of insanity.
Carroll said that he and his coworkers counted a total of 6 spent shotgun shells, 65 .223 spent casings from a rifle and 5 .40 caliber casings from a handgun.
Unfired bullets were discovered inside of several magazines for the different kinds of ammunition, and one drum magazine for the rifle that was partially emptied.
We've heard in previous hearings that the drum magazine and rifle jammed, which likely explains why the other magazines were abandoned throughout the hallway of Theater 9.
