Through witness testimony, prosecutors this week laid out a timeline of the actions accused Aurora theater shooter James Holmes took in the months before the July 20 attack. The earliest date mentioned was April 19, when he set up a Match.com profile. The last was July 19, when Holmes allegedly took photos of himself with shock-orange hair and posing with weapons. In between, he amassed a small arsenal. Continue for a full timeline.
We've compiled this timeline based on testimony from witnesses at a preliminary hearing in Holmes's case, which took place January 7, 8 and 9. Most of the witnesses were police officers who testified about the evidence they'd accumulated against Holmes.
June 2011: Holmes, who grew up in California, enrolls at the University of Colorado Denver as a neuroscience graduate student.
April 19, 2012: Holmes creates a Match.com account whose headline eventually reads, "Will you visit me in prison?" and features photos of him with orange hair.
May 10: Holmes buys two six-ounce tear gas grenades from an online retailer, according to ATF special agent Steven Beggs, who chronicled Holmes's weapons purchases.
May 22: Holmes buys a Glock .40 caliber pistol from a Gander Mountain store.

June 6: Holmes buys two pairs of handcuffs, a military first-aid kit and road stars meant to puncture tires from an online retailer.
June 7: Holmes fails his oral exams at the University of Colorado. Prosecutor Karen Pearson has said that his poor performance on those key exams is "very much relevant to what happened afterward."

July 19, 5:17 p.m.: Holmes allegedly photographs his ballistic gear arrayed on his bed. On top of a red sheet, it's possible to see a tactical vest on which are strapped several rifle and handgun magazines, a gas mask, a gas canister, a helmet and three guns -- a rifle, a shotgun and a handgun -- among other gear.
July 19, 6:22 p.m.: Holmes allegedly takes a photo of himself wearing a black skull cap with two red curls of hair sticking out above each ear, almost like horns. He's wearing black contact lenses that make his irises appear entirely dark and he's sticking his tongue out.
July 19, 6:25 p.m.: Holmes allegedly takes another photo of himself, this time with what a witness described as "a large toothy grin." He's holding the muzzle end of a handgun near his chin, at an angle pointing toward the ceiling. He looks gleeful.
July 19, 6:31 p.m.: Holmes allegedly continues his photo session, this time holding one of the homemade bombs found in his apartment. A unlit fuse sticks out the top of the bomb. He poses with his lips in a tight "O," as if he's blowing out the fuse.

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.
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."

He's wearing a torn T-shirt and boxer shorts. Police have put paper bags over his hands to preserve gunshot residue. An officer assigned to watch him reports to Aurora police detective Craig Appel that Holmes begins "moving his hands in a talking-puppet motion."
After Holmes drinks a cup of water, the officer reports that he starts playing with the cup, "trying to tumble it," Appel said. Holmes also reportedly pulls a staple out of the table and tries to stick it in an electrical outlet. He is not tested for drugs or alcohol because police don't suspect he's under the influence, Appel said.
Holmes tells the police about the elaborate system of explosives he's set up in his apartment. FBI agent Garrett Gumbinner testified that Holmes "said he had rigged his apartment to explode or catch fire to send resources to his apartment rather than to the theater." He'd programmed his computer to play 25 minutes of silence followed by loud music, "hoping that would cause a disturbance" that would prompt someone to call the police.
Among the explosives found in his apartment are a thermos of glycerin perched over a frying pan full of chemicals that would cause heat and flames if mixed with the glycerin and jars filled with homemade napalm and bullets, topped with smokeless powder and a homemade version of a powder that burns so hot it can't be extinguished with water. Police also found several homemade bombs made out of nested fireworks shells filled with smokeless powder, gasoline and oil. The carpet was also soaked with gas and oil.
Gumbinner said Holmes described three so-called initiating systems, or systems that would trigger the explosives to go off. One was a pyrotechnic firing box usually used for fireworks. Holmes placed the remote control to the box outside his apartment near the dumpster next to a remote-control car and on top of a boombox in a trash bag. Holmes told police that the boombox was set to play forty minutes of silence followed by loud music. Presumably, the idea was that the music would attract someone, who would then try to play with the car and unwittingly set off the explosives in Holmes' apartment.

July 23: Holmes appears in court for the first time, wearing a maroon colored jumpsuit and a dazed look on his face. He's advised of his rights and told he'll be held without bond. Media from all over the world reports on Holmes's orange hair and glassy-eyed expression. At some points during the hearing, Holmes appears to nod off.
July 30: Holmes is back in court, this time to be officially charged with murder. Prosecutors announce that he faces 142 counts: 24 counts of first-degree murder, 116 counts of attempt to commit first-degree murder, one count of possession of explosive devices and one sentence enhancer for a crime of violence.
October: Prosecutors add 24 more attempted murder charges related to twelve more victims, bringing the total number of counts against him to 166.
January 7, 8 and 9, 2013: Holmes is in court for a three-day preliminary hearing in which prosecutors lay out the evidence against him in the hope of proving probable cause. Read our coverage of day one, day two and day three.
January 11: Holmes is due back in court at 9 a.m. for what Judge William Sylvester called a status hearing/arraignment, which means Holmes may enter a plea. His public defenders have made many references to his "mental illness" over the past months, and he's widely expected to plead not guilty by reason of insanity.
