Police in Aurora, Colorado, have diffused the booby traps at shooting suspect James Holmes' apartment and are sending evidence to FBI headquarters at Quantico, FBI special agent James Yacone said at a news conference Saturday afternoon.
"It went very, very well," Yacone said. "The threat has not been eliminated. It has been significantly reduced."
Authories also continue gathering evidence and investigating the theater where Holmes allegedly opened fire early Friday morning, killing 12 and injuring 58.
They expect to finish on Monday, and return control of the Century 16 theater to its owners on Wednesday.
Police also said the Arapahoe County coroner's office has identified all 12 victims Saturday afternoon.
The youngest identified victim was a six-year-old girl.
Her name was Veronica Moser-Sullivan and she was shot alongside her mother, Ashley, 25. The little girl died at the scene, and her mother, who is slipping in and out of consciousness at a nearby hospital, does not yet know her daughter died, according to a report in the Denver Post.
Federal and local bomb experts began defusing an elaborate web of booby traps in Holmes' apartment early Saturday morning that surprised even veteran FBI bomb experts, who said they "rarely [encounter] anything this complex."

Police and authorities entered the apartment with a robot and disabled a tripwire stretched across the front door of the 800-square-foot dwelling. Next, they defused the trigger on a volatile mixture of chemicals that, if triggered, would have exploded in a blast or ignited.
Aurora Police Chief Dan Oates said the bomb team will soon enter the apartment to neutralize any remaining traps and collect evidence, which will be processed at the high-level security Marine Corps base at Quantico.
After encountering the deadly devices in Holmes' apartment, blocks away from the theater, Oates was visibly angered.

"This apartment was designed to kill anyone who entered," he said, adding that it was apparently designed to kill responding police officers. "What has happened to our city, what has happened to the wonderful people that live here and also what he threated to do to one of our police officers — there's no question what the intent was for anyone who designed [that]."
"If you think we're angry," he added, "we sure as hell are angry."
Among the other victims of the shooting:
Alex Sullivan, 27, was celebrating his birthday by attending the late night screening.
Matt McQuinn, 27, died to save his girlfriend, 27-year-old Samantha Yowler, shielding her from bullets with his body. She was shot in the knee, but survived.
Jessica Ghawi, the 24-year-old aspiring sportscaster who has captured much media attention as the first identified victim, narrowly escaped death weeks earlier when a gunman shot seven people at a Toronto food court. She died in the theater.

John Larimer, 27, was a sailer in the U.S. Navy.
The name of Rebecca Wingo, 32, came out when her father posted on Facebook: "I lost my daughter yesterday to a mad man, my grief right now is inconsolable, I hear she died instantly, without pain, however the pain is unbearable."
The coroner later identified Jesse E. Childress, 29, a U.S. Air Force reserves cyber systems operator who was one of two that died at a nearby hospital.
Another serviceman, Jonathan T. Blunt, 26, died covering his girlfriend with his body. She later told the Los Angeles Times that "he took a bullet for me."
