As we said, at least 14 dead, 50 injured. The suspect, a young man, 24 years-old. Eyewitnesses describe him as armed for battle -- a rifle, a handgun, a shotgun and smoke bombs -- wearing a bullet proof vest and a gas mask -- police believe now he acted alone, but they continue to search the entire area. The suspect's apartment complex has been evacuated -- reports that explosives were found there."

"GMA" spoke to many eyewitnesses throughout the morning. Amy Robach spoke to Lamar Lane, a 21-year-old who was inside the theatre.
