A married Florida principal has been arrested after she was caught in a car partially undressed with a student and police found marijuana in the vehicle. 45-year-old Krista Morton, the principal at Mavericks High School in Kissimmee, was arrested Wednesday in Palm Springs. Police responded to a report of people involved in sexual activity in a car and found Morton and an 18-year-old man. When Morton opened the door, her shirt was unbuttoned, exposing part of her chest. Morton told police she had just met the teenager, but the student admitted she was his principal. Police say they could smell marijuana inside the vehicle and found the drug and other paraphernalia. Morton and the student were arrested. She has been charged with possession of marijuana.
