COLUMBIA, S.C. -- Deputies said the sister of South Carolina church shooter Dylann Roof was arrested Wednesday for bringing drugs, pepper spray, and a knife to her school.
The Richland County Sheriff's Department told WIS-TV 18-year-old Morgan Roof was arrested after an administrator at A.C. Flora High School had 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, and she is not allowed to return to the school.
Investigators said Morgan Roof also posted a Snapchat that alarmed fellow students but was not arrested for it.
ABC News reports the snap read: "Your walking out of the allowed time of 17min, they are letting you do this, nothing is gonna change what tf 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."
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.
