There's about 100 FBI agents on the scene assisting with investigation, according to the local special agent in charge. Once apprehended the gunman told authorities that there were explosives in his North Aurora residence. Investigators rushed to the apartment complex, which was quickly evacuated and is now under lockdown. A senior official who is monitoring the situation in Washington said that early guidance based on the early snapshot of this man's background indicated that this act does not appear to be linked to radical terrorism or anything related to Islamic terrorism. In a statement, President Obama said, "Michelle and I are shocked and saddened by the horrific and tragic shooting in Colorado. Federal and local law enforcement are still responding, and my administration will do everything that we can to support the people of Aurora in this extraordinarily difficult time. We are committed to bringing whoever was responsible to justice, ensuring the safety of our people, and caring for those who have been wounded." Investigators confirmed that explosives were found. It is unclear if they were scheduled to detonate or if it was part of a stockpile.
