A mother from Addison faces charges of heroin possession after she was discovered unconscious during a school trip with her daughter. Twenty-eight-year-old Stephanie Bailey is charged with possessing four small bags of heroin, and drug paraphernalia. Police say she was with her 7-year-old daughter and other children on a school trip to Pioneer Village. She was serving as a parent chaperon. Bailey says she did not take heroin while on the school trip, but a police complaint says she did admit taking it the day before.
