Oates says pictures from inside the apartment are fairly disturbing and the devices look to be sophisticated.

FBI agents and police used a hook and ladder fire truck and put a camera at the end of 12-foot pole inside the apartment.

The apartment is about four miles from the theater where 12 people were killed and 59 were wounded.
