According to HISD, Lori Cotton-Noel came to the school on Thursday to meet with the assistant principal about what the district calls an alleged incident. HISD says Cotton-Noel apparently grew angry, displayed a gun clip and threatened to use a firearm.
School police were called and now charges have been filed against Cotton-Noel.
Eyewitness News spoke with her husband who says one of his children has been bullied at Marshall consistently, even threatened with being shot by other students, and he says the administration has failed to address it. On Thursday, they were going to another conference to ask for help.
"She just wanted to let it be known, just like they're threatening my daughter with shotguns and pistols and spraying mace in her face, when they made one shotgun, they did not stop making them," he told Eyewitness News.
He claims there was not a direct threat made by his wife against the administrator.
Cotton-Noel, 40, came to school Friday afternoon to pick up her kids. Instead, she learned in a letter sent home to school parents that she'd been charged with a felony.
Students were sent home with letters to parents notifying them of this incident, saying in part, "Ensuring the safety of each of our students is one of our main priorities, and in this case, the safety of the students was never compromised. While we believe this is an isolated incident, we want to remind all of our students and parents about the importance of appropriate behavior at all times, especially while on our campus."
HISD says Cotton-Noel has been banned from all HISD campuses.
