Those were the words found on the walls of a restroom at Plaquemine Senior High School on Wednesday, November 10, according to the Iberville Parish Sheriff’s Office.

There was no school for students on Thursday and Friday at Plaquemine Senior High School.

A full investigation in conjunction with law enforcement has been conducted and the origination of the threat has been discovered. Out of an abundance of caution we will have additional security on site.

Investigators determined a person of interest who happened to be from out of town.

That person of interest turned out to be a 14-year-old juvenile.

The juvenile was arrested after admitting to writing the threat on a bathroom wall.

The 14-year-old was subsequently returned to their parents.
