A former Lanier Charter Career Academy student who took his terroristic threat case to the Georgia Supreme Court last year was sentenced to probation Thursday in Superior Court. Devon Major was charged after threatening to get “the chopper out and make Columbine look childish” in September 2014 on a Facebook post. A chopper is a slang term for a gun, and the 1999 Columbine shootings killed 13 people in Littleton, Colo.
