California chemistry teacher Margaret Gieszinger surprised her class when she took scissors to a male student’s hair earlier this month. As she cut his hair, the 52-year-old sang the national anthem. Gieszinger is behind bars after being arrested for alleged child endangerment. Inside Edition spoke with her husband, Peter, about the bizarre event. “This is beyond anything I could imagine her doing,” he said, adding that he believed it was brought on by stress.
