 We're told it's not clear if Crooks had a gun with him at that point. According to multiple sources, a law enforcement officer had also previously seen Crooks on the grounds and called him in as a suspicious person with a picture prior to 545. Our sources tell us that an officer checked the grounds for Crooks at that point but did not see him where the first picture was taken. 26 minutes after the second picture of Crooks was taken by law enforcement and the information called in, shots were fired from the roof of the American Glass Research Building. Seconds later, Secret Service sniper returned fire and killed Crooks.
