The sister of Charleston church shooter Dylann Roof was arrested Wednesday after she brought weapons and drugs to her school. A school resource officer reportedly detained Morgan Roof, 18, and found she was in possession of marijuana, pepper spray, and a knife at C. Flora High School in Columbia, South Carolina. The Post and Courier also reported Morgan Roof posted a disturbing Snapchat on Wednesday during the nationwide school walkout in protest of gun violence, saying: “Your [sic] walking out for the allowed time of 17min, They are letting you do this, nothing is going to change what tf [sic] you think it’s gonna do? I hope it’s a trap and y’all get shot we know it’s fixing to be nothing but black people walkin out anyway.” Roof was charged with possession of marijuana and two counts of carrying weapons on school grounds. A judge set a bond of $5,000 under the condition Roof does not return to the school.
