Movie Massacre: Shock, Sadness, a Search for Clues A Colorado suburb shocked and saddened by a deadly shooting spree at a midnight unveiling of the latest Batman movie grieved for the victims while authorities sought a motive and a safe way to reach clues inside the suspect's apartment, still apparently rigged with an elaborate booby-trap. Police grimly went door to door late Friday with a list of the victims killed in the worst mass shooting in the U.S. in recent years, notifying families who had held out anxious hope that their loved ones had been spared inside the packed theater near Denver. Twelve people died and 58 were injured in the attack early Friday, a few of those not by gunfire but in the chaos that ensued as the audience tried to flee the smoke-filled theater, authorities said. Among the wounded, 11 were listed in critical condition. The deceased victims included 23-year-old Micayla Medek, said Anita Busch, the cousin of Medek's father. The family took the news hard, but knowing her fate after waiting without word brought them some peace, Busch said. "I hope this evil act, that this evil man doesn't shake people's faith in God," she said. Besides Medek, relatives confirmed that Alex Sullivan and Jessica Ghawi were among those killed, Sullivan on his 27th birthday.

A gunman wearing a gas mask set off an unknown gas and fired into a crowded movie theater at a midnight opening of the Batman movie "The Dark Knight Rises," killing at least 12 people and injuring at least 50 others, authorities said. Hours after the shootings, it remained unclear what drove the suspect, identified as 24-year-old James Holmes, to fire round after round at the unsuspecting audience watching "The Dark Knight Rises." Aurora Police Chief Dan Oates said Holmes used a military-style semi-automatic rifle, a shotgun and a pistol that he had bought at local gun stores within the last two months. He also recently purchased 6,000 rounds of ammunition over the Internet, the chief said. The suspect's stellar academic record, apparent shy demeanor and lack of a criminal background made the attack even more difficult to fathom. It also wasn't known why the suspect chose a movie theater to stage the assault, or whether he intended some twisted, symbolic link to the film itself. The new Batman movie, the last in the trilogy starring Christian Bale, opened worldwide Friday with midnight showings in the U.S. The plot has the villain Bane facing Bale's Caped Crusader with a nuclear weapon that could destroy all of fictional Gotham. Oates would not confirm that information, but did say he had spoken to Kelly. Near the entrance to the Aurora theater's parking lot, a makeshift memorial of 12 candles sat in a row near piles of flowers. A sign read, "7/20. Gone Not Forgotten. An emotional Gov. John Hickenlooper said earlier Friday that people would not be defined by the tragedy. "We are clear that we are going to rise back and lift ourselves above this," he said.
