COLUMBIA, S.C. (CBSLA/CBS News) -- Deputies say the sister of church shooter Dylann Roof has been arrested for bringing drugs, pepper spray and a knife to her South Carolina school.
The Richland County Sheriff's Department told CBS Columbia, S.C. affiliate WLTX-TV that 18-year-old Morgan Roof was arrested Wednesday after an administrator at A.C. Flora High School contacted a school resource officer.
Roof is charged with marijuana possession and two counts of carrying weapons on school grounds. A judge set her bond at $5,000. She was screened for a public defender. She is not allowed to return to the school.
Investigators say Roof also alarmed fellow students when she put out a post on Snapchat regarding the nationwide school walkouts on Wednesday.
"Your walking out for the allowed time of 17min, they are letting you do this, nothing is gonna change what tf you think it's gonna do?" the caption reads. "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's sister was not arrested for the post.
School principal Susan Childs posted a letter to parents on the school's Twitter page explaining what occurred while students walked out to remember the 17 killed in the Parkland, Florida, Valentine's Day school shooting.
Dylann Roof was convicted of fatally shooting nine African-American parishionersat a Charleston church in 2015. He's been sentenced to death.
