James Holmes: Read timeline of his actions before and after Aurora theater shooting

July 20, approximately midnight: Holmes can be seen on a surveillance video entering the Century 16 theater. He's wearing a black skull cap, dark pants and a light-colored button-down shirt. He holds the door open for two people who enter behind him.

July 20, 12:03 a.m.: Holmes attempts to scan his phone to retrieve his movie ticket. He ends up scanning it twice more, presumably because he's having technical difficulties. After successfully retrieving his ticket and giving it to the ticket-taker, Holmes walks to the concession stand and, as one witness said, "stands there for several minutes." He doesn't buy anything. He then walks off-camera toward theater nine.

July 20, before the movie starts at 12:20 a.m.: A witness sitting in the second row tells police that he observed a man in a black bandana or cap who was sitting in the front row take a phone call, walk toward the emergency exit and prop it open with his foot.

July 20, approximately 12:38 a.m.: Holmes is accused of entering the theater through the emergency exit, which was propped open with a plastic tablecloth holder. Wearing enough black ballistic gear to protect his entire body and carrying three guns, he's accused of throwing a canister of tear gas into the audience. Soon afterward, prosecutors say he opened fire, spraying the audience with bullets from a shotgun, a rifle and a handgun. Moviegoers began screaming and scattering but not before some of them were hit. Twelve people were shot and killed and seventy others were wounded from a combination of bullets, tear gas and injuries sustained as they tried to flee.

Outside the theater that night.

July 20, a few minutes later: Holmes is arrested outside the theater. Police find him standing by his white two-door car, which is parked as close as possible to the emergency exit door for theater nine. They first mistake him for a SWAT officer but soon realize he's not because he's "just standing there," Aurora officer Jason Oviatt testified.

Holmes is wearing a gas mask. Figuring that the only person who would have known to wear one would be the suspect, Oviatt aims his gun at Holmes as another officer shouts for Holmes to put his hands up. Holmes does so "immediately," Oviatt said.

Holmes doesn't resist as the officers order him to lie face-down and handcuff him. "It was just complete compliance," Oviatt testified, adding that Holmes didn't even display the "normal tension" of a person being arrested. He seemed "disoriented and out of it," Oviatt said, as if he were "very detached from it all."

The officers eventually strip him in order to search him for weapons. When asked whether he has any, police testified that Holmes said he had explosives in his apartment. Asked if they were set to go off, Holmes reportedly answered, "If you trip them."
