For Sharon Waters and her 14-year-old son, this school year at John Quincy Adams Middle School in Metairie has been anything but calm.

"I was horrified that a child would tell my son through social media he was going to kill him," said Waters.

Waters' 14 year-old-son received a threat through an Instagram message on May 9th from another student in his class, according to the Jefferson Parish Sheriff's Office. The threats show a picture of gun, which deputies later determined was a BB gun, pointed at the camera. The caption says “imma smoke you keep playin.” The student was arrested but was released and in just a short time was back on campus.

"He went to school the very next day with vengeance on his mind toward my son,” said Waters. “He walked up to my son, put his hand in face and he told him ‘The next time it will be my gun. I am going to find out where you live and I am going to kill you.'”

After that the student was arrested again. This time instead of a cyber stalking charge he was booked on simple assault, according to the Jefferson Parish Sheriff's Office.

"Why was this kid allowed back in school after you knew he was threatening one of your students?" Waters wonders.

This isn't the only threat against her son, according to Waters. She says in early February, another student threatened him with a knife through Snapchat but since the messages disappear on that social media platform there was no physical evidence. That student is still in her son's class, Waters said.

"It's a clear threat. We have evidence. There are witnesses so therefore you (the school) need to take who is making the threats and take them out of the school."

It's still unclear if the student who made the latest threats has been admitted back into class. According to Waters, he was not in school Tuesday. The school district didn’t say why the student was allowed back on campus after the first threat but did say they are working with the sheriff's office and that appropriate disciplinary action will be taken.
