Hundreds of students walked out of a St. Louis high school last week to protest horrific racist graffiti someone had painted on school walls. Not more than a week later, the parents and community received a letter from the superintendent noting they identified the culprit.

The student who wrote the racist hate speech at Parkway Central High School prompting a schoolwide walk-out was a Black student. The motivation behind the graffiti is not clear, but the racial slurs were written “all over the stalls, on the ground, on the mirrors” reported the local Fox2 station.

The Parkway School District confirmed to Fox2 that the student involved was Black. In the letter addressed to the “Parkway Community” on September 28, stated:

“The investigation has concluded at Central High School related to this incident. The evidence led to a single student and the student admitted writing the messages.

The student responsible is not white, however this does not diminish the hurt it caused or the negative impact it has had on our entire community.”

The letter added “regardless of the reason or the individual responsible, these acts are a significant violation of multiple codes of conduct outlined in our policies. The student is facing severe disciplinary consequences and referral to law enforcement for investigation.”
