NBC News President Steve Capus said the network received the package in Wednesday morning's mail delivery and immediately turned the material over to FBI agents in New York. The FBI is assisting Virginia State Police in the investigation.
The package included a long, “rambling, manifesto-like statement embedded with a series of photographs,” Capus said. The material is “hard-to-follow ... disturbing, very disturbing — very angry, profanity-laced,” he said.
Among the materials are 23 QuickTime video files showing Cho talking directly to the camera about his hatred of the wealthy, Capus said.
