Officials at a Christian school in New Jersey are trying to track down the author of two hate-fueled notes found in the locker of a black student, including one that read: “I hope you die n—-r.”

The principal at Gloucester County Christian School in Sewell asked students at the private K-12 school to submit writing samples in hopes of identifying the penmanship of a suspect, but a match has yet to be made, Philly.com reports.

“It’s very disturbing,” the school’s campus administrator, Pastor John Mark Turner, said Tuesday. “We want the kids to be polite and courteous and understand that their words hurt people.”

The Mantua Police Department said they’re investigating after the incident was reported by the student’s mother, Sharon Jackson.

The woman also informed officials at the Camden County East Branch of the NAACP about the notes last week, according to chapter president Lloyd Henderson, after the woman’s son found a second note on his locker on Oct. 18 that read: “I hope you die n—-r.”

The student disregarded the note left at his locker five days earlier, Henderson said.

The boy and his sibling, both of whom are eighth-grade honors students, have since withdrawn from the school and are now attending public school in a neighboring county, according to Jackson, who characterized the incidents as “very disheartening.”

“We thought that was as near to being a perfect environment for our children,” she told Philly.com. “I was very surprised that they would have to experience hatred in a Christian school.”

Just 7 percent of students at the school are black, according to Turner.

Turner and Henderson agree the current climate on race relations in the country may have contributed to what motivated the notes.

“Unfortunately, it’s a culture now where you believe you’re not going to be slammed,” Henderson told Philly.com. “People believe they can be free now with their racist, biased attitudes.”
