Batman Colorado shooting: Batman mask and film poster 'found in James Holmes's flat'

A Batman mask and film poster have reportedly been found in the apartment of alleged cinema gunman James Holmes, although police declined to confirm the reports.

A Batman mask and film poster have reportedly been found in the apartment of alleged cinema gunman James Holmes.

The 24-year-old Holmes is accused of killing 12 people and injuring 58 others when he opened fire, dressed all in black and in full body armour, at a midnight screening on Friday of the new Batman movie "The Dark Knight Rises."

CNN and the Los Angeles Times both cited sources as saying that a Batman mask and poster had been found in his apartment, which police only entered on Saturday after defusing a complex system of booby traps.

But the Aurora Police Department declined to confirm or deny the reports.

"We are not talking about any of the evidence that was released, or obtained from the apartment," a spokesman told AFP, adding that he understood at least one media outlet claimed to have a long-lens image of the Batman items.

"We have no way to confirm it. All the evidence that was obtained was taken away and filed," he added.
