After clearing “all hazards” from the booby-trapped apartment of a gunman who went on a shooting spree at a US cinema hall, police entered the “designed to kill” house where the suspect had planned the deadly attack with “calculation and deliberation” for months.
Two days after 12 people, including a six-year-old girl, were killed and 58 others wounded during the premiere of new Batman movie 'The Dark Knight Rises' at an Aurora theatre in Denver, Colorado, US President Barack Obama was set to visit the injured and families who lost their loved ones.
Last night, investigators carried out “controlled detonation” in Holmes' booby-trapped one-bedroom apartment after which they entered the house in a bid to find out clues to the motive behind the deadly attack.
At least 30 improvised explosive devices were found when police entered the Denver apartment of Holmes, who was arrested after the shooting. Police said Holmes may have been planning the attack for a long time as he received a high volume of deliveries over the past four months to both his home and work addresses.
