She is a single woman who was unknowingly targeted to die by a murderer named Roger Hicks.
Allison lived under the radar with no dog and kept her neighbors at a distance. She went to Roger in hopes of buying a new car. When Roger met her, he ran a background check on her and found everything he needed to know in preparation to kill her. Although Roger was going to kill her, she was saved from this fate when Dexter Morgan captured Roger in the dealership parking lot by garroting him from behind.
