Nothing is known about Stevie's life prior to or as the outbreak began.
At some point during the apocalypse, Stevie came in contact with Clayton and decided to join his noble cause of helping other people by leaving boxes of supplies on the road.
Stevie is delivering a box at a mile marker when Martha approaches her. Martha corrects Stevie on a spelling mistake written on the box and Stevie corrects it. She thanks Martha for the help, but Martha says she doesn't. Stevie asks what she doesn't, and Martha repeats she doesn't help. Stevie is confused by the statement, and is taken by surprise when Martha stabs her through the throat, killing her. She then reanimates and Martha uses her to kill a truck driver. She is never seen again after that, but since Martha released Purvis after using him to kill Quinn, she most likely released Stevie as well, meaning Stevie may still be undead.
