ATLANTA — Three people face charges after violent clashes with campus police at Georgia Tech following a vigil for a student fatally shot by officers, a university spokesman said Tuesday. Police shot and killed Scout Schultz, 21, Saturday night after the fourth-year student called 911 to report an armed and possibly intoxicated suspicious person, the Georgia Bureau of Investigation said. The GBI on Tuesday identified the officer who shot Schultz as Officer Tyler Beck but did not provide any other information about him. On Monday night, Georgia Tech issued alerts urging students to shelter indoors because of violent protests.
