Police said they set off an explosion Saturday at the booby-trapped apartment of the Colorado theater-shooting suspect, significantly reducing the danger. "We believe we have eliminated the major threats there, but we still have some more work to do," Aurora Police Chief Dan Oates was quoted as saying by the United Press International (UPI). Oates said James Holmes' apartment undoubtedly was "designed to kill whoever entered it," USA Today reported. FBI Special Agent John Yacone said the effort to disarm the explosive devices "went very, very well, but the threat has not been completely eliminated. It has been significantly reduced." The Los Angeles Times reported the controlled detonation was set off inside the Aurora apartment after several blocks of nearby Peoria Street were evacuated.
