Students told KFSN-TV that Gieszinger entered her first period chemistry class on Wednesday with a pair of scissors and declared it was haircut day. In video posted to social media, a student can be seen sitting in a chair at the front of the class. Gieszinger appears to cut off a chunk of his hair and toss it behind her, all while singing the national anthem. The student tries to stand up, but Gieszinger says "you're not done," and motions for him to sit back down.
Later in the video, Gieszinger calls out to other students and appears to try to cut a female student's hair. Students scream and flee the classroom as Gieszinger continues to sing loudly.
