(Portland, OR) -- The Parkrose High School student accused of bringing a loaded shotgun to his campus and pointing it at a classroom full of his peers is pleading not guilty. Court records show 19-year-old Angel Granado-Díaz pleaded not guilty to charges of reckless endangerment, possession of a firearm and carrying a firearm into a public building during his first court appearance yesterday, which was also his birthday. Bail was set at 500-thousand dollars. Witnesses say Díaz appeared in the doorway of a government class on Friday wearing a black trench coat and holding a shotgun. A security guard tackled him to the ground before any shots were fired. No injuries were reported.
