(Newsroom America) -- Police in Colorado say 59 people were wounded in the theater shooting in Aurora and the death toll remains at 12, while the apartment of the alleged shooter James Holmes is booby trapped with chemical and explosive devices.
Aurora Police Chief Daniel J Oates gave further details on the attack at a press conference a short time ago, saying Holmes was dressed in black, and was wearing a black ballistic helmet, ballistic vest, ballistic leggings, a black gas-mask and black tactical gloves.
Chief Oates said he entered the theater about midnight and set off two devices to distract the crowd which were "some sort of irritant or smoke." It is still not clear where Holmes entered the theater.
Holmes allegedly opened fire in the theater with an AR15 assault rifle, Remington 12 gauge shotgun and a 40 caliber Glock handgun. Another 40 caliber Glock was found in his car.
The shooting took place in Theatre 9, but bullets penetrated into another theater where at least one person was hit.
Aurora police arrived within a minute to a minute and a half of the first 911 call, where Holmes was apprehended in his car at the back of the theater.
Chief Oates said they currently had no capability of calculating how many rounds were fired.
"There were many, many rounds fired," he said, adding police would be at the crime scene for some time.
Police were confident the gunman acted alone and were not looking for any other suspects, but inquiries were continuing.
Meanwhile Chief Oates said Holmes' apartment building and other nearby buildings have been evacuated after police determined it is booby trapped.
"His apartment is booby trapped with chemical and incendiary devices ... it may be resolved in hours or days but I don't know how we will handle that," he said.
He also warned media about what they reported from social media, saying police were analysing all social media and there were already "lots of pranks" out there.
