The note was found on the wall of a girls bathroom stall by school officials at about 2:30 p.m., Columbia County sheriff’s Capt. Steve Morris said.
The note insinuated its author was “going to blow up the school,” Morris said.
It was written in pencil in small handwriting, Columbia Middle Principal Steven Cummings said.
Bomb-detection dogs were scheduled to search the school Thursday afternoon, Cummings said.
“Parents and students can expect to see an increased law enforcement presence when the school opens (today),” Morris said in an e-mail.
Should the author of the note be discovered, Cummings said that pupil would be immediately suspended then face expulsion before the school system hearing officer.
A similar incident happened last week at Evans High School.
Two notes threatening violence were found March 1 in bathroom stalls. One of the notes was written by someone threatening personal harm. The second note, found in a girls bathroom, alluded to a shooting happening at the school March 2.
The school was placed on lockdown, and deputies searched students as they entered.
Authors of the threatening notes can be charged with terroristic threats and acts in addition to disrupting a public school, Morris has said.
