Neighbor Banged On Apartment Door Over Loud Music
A neighbor of the mass shooting suspect thinks the man, James Holmes, may have tried to lure someone into his booby-trapped apartment to create a diversion during the shooting spree.
The neighbor, Chris Rodriguez, told 7NEWS, he and his girlfriend started hearing loud techno music coming from above them at midnight.
"Usually the complex is very quiet, nobody has parties, so that was the first time we actually had a party or a lot of noise at the complex," said Rodriguez.
After about 15 minutes, Rodriguez's girlfriend decided to knock on the door and ask them to turn the music down.
"She went upstairs to the apartment, and she knocked on the door pretty hard, she knocked two or three times and yelled into the door, 'Hey, can you turn that music down, we are trying to sleep,'" said Rodriguez.
Rodriguez said that no one answered and his girlfriend didn't even hear any footsteps.
While she was listening at the door, she noticed that the door moved.
"The door moved a little bit, and the handle jiggled a little, and she was contemplating going into the apartment, but something told her don't do it," Rodriguez said.
Rodriguez said his girlfriend then went back to their apartment and called police.
The apartment is the home of 24-year-old James Holmes.
Police said Holmes walked into a crowded theater in Aurora and set off two devices with some type of irritant or smoke.
He was dressed in all black and was wearing a ballistic helmet, tactical vest, throat protector, groin protector, black tactical gloves and a gas mask, police said.
The suspect had four weapons. In the theater he fired off an AR-15 rifle, a Remington shotgun and a 40-caliber Glock handgun, police said. Another 40-caliber Glock handgun was found in his white Hyundai.
7NEWS has learned Holmes legally bought the firearms at a Bass Pro Shop and Gander Mountain Guns within the last several months. The first gun was bought in May.
Investigators said they have no idea how many rounds were fired, but that it was many.
Police said Holmes was arrested one minute to one and a half minutes after the first 911 call reporting the shooting at a theater in Aurora.
Holmes is scheduled to appear in court in Arapahoe County Monday morning.
Witnesses told 7NEWS officers started pulling up to the apartment around 1 a.m. and then evacuated the building.
7NEWS has learned that Holmes lived in apartment 10.
Police said they are confident that Holmes acted alone, but they said they will do a through investigation to confirm that.
Police in San Diego said Holmes' family is very upset.
"It has taken everyone by surprise," said an officer outside the family's home.
Investigators said the family is cooperating with law enforcement in San Diego and Colorado.
"I need to call police and I need to fly out to Colorado," said Arlene Holmes during that call. Holmes' father left the family home and arrived at Denver International Airport at 1:30 p.m. He was escorted off the jetway through a side entrance.
Holmes Was CU Neurosciences Student
The Call7 Investigators have learned Holmes moved from San Diego to Colorado about a year ago. His mother told reporters in San Diego that her son moved to Colorado to pursue a PhD.
CU-Denver confirmed that Holmes took classes for one year and was in the process of withdrawing from the graduate program in neurosciences.
CU-Denver issued a statement that said:
