Alaina Ferguson, a 23-year-old math teacher in Texas, was arrested and charged with sexual assault on Nov. 30 after her Snapchats with her 16-year-old student led to a sexual relationship between the two. Ferguson was released from Collin County Jail Thursday after posting a $100,000 bond. She is required to always wear an electronic tracking device, take down all of her social media accounts and cease from going on the Internet completely.
