Her backstory revealed that following the murders of Charity's parents T.C. and Hope (which were committed by Charity's boyfriend Harley Dimmoch—the film's hidden secondary antagonist), Alicia masterminded Melba's murder, which Charity perpetrated, resulting in the callous orchestrator inheriting the Julius family fortune—after which she split the money between herself and her two accomplices. After her sister's death, the evil Alicia told her maternal great-niece that she "was [going to] die anyway" and also posed as Melba; in the film's prologue, she informed the police of the "disappearance" of her "daughter," "son-in-law," and "granddaughter." Meanwhile, Charity moved to Harley's house in Vancouver, Washington, resulting in her being assumed dead along with her parents. Four years later, Alicia reluctantly sold her house in Lawrenceton, Oregon, to Aurora Teagarden—all while evading questions about the Julius family case without raising any suspicions and acting like she was a grieving woman who still believed that her missing relatives would come back.
However, after the three victims' skeletons were found in the house's attic, the villainess' machinations began to unravel. It was discovered that while two of the skeletons were those of a middle-aged man (T.C.) and a middle-aged woman (Hope), the third skeleton wasn't a teenage girl's, but that of an elderly woman. A web search conducted by Sally Allison led to her realizing that Alicia was posing as Melba, and while Martin Bartell (Aurora's boyfriend) tracked Harley around Vancouver, he spotted him meeting up with the deceptive woman. She had an argument with her henchman about Aurora, with the former ultimately being ordered by the latter to kill her before she stated she would see him at his house. At that moment, the crafty criminal got into a cab in order to personally make sure that her handiwork had succeeded.
The cab in question approached the house just moments after Charity and Harley were placed under arrest. Alicia frantically told the driver of the cab to pass by her intended destination once she registered what was going on, but Lynn Smith (who worked the case when it was originally reported four years ago) instructed said driver to stop the vehicle and arrested her as well. Defeated, she snarled at Aurora and stated that it "was all [her] doing," adding that she should have never sold the house to her.
