While Virginia (who was in Seattle to visit Kelly) appeared heartbroken by her daughter's death, it was later revealed that Virginia was behind Kelly's murder. As revealed in the case's climax, Virginia had grown frustrated with Kelly for cutting off contact from her and her husband Hector after moving to Seattle to pursue journalism, with her feelings become more intense when Hector became sick and eventually died. Kelly's refusal to attend her father's funeral was what eventually drove Virginia over the edge, leading her to kill Kelly on the bus during a confrontation with her, stabbing her in the neck with a pocketknife.
Virginia left the nasal spray she used for her pollen allergy behind on the bus, with her nasal hairs on the bottle being among the evidence proving her guilt in Kelly's murder. After initially denying everything upon being interrogated by the player and Jack Archer, Virginia broke down and confessed, proclaiming that Kelly was no longer the daughter she raised. But after being reminded by Jack that she had in fact killed her daughter, Virginia broke down in tears as she bemoaned the crime she had committed. During her trial, Virginia pleaded guilty and told judge Nigel Adaku that she would accept the sentence he gave to her. After factoring Virginia's age and the possibility that she was suffering from dementia, Adaku sentenced that Virginia spend the rest of her years in a high security medical institution.
- Virginia Purnell is similar to Miranda Galguera, a villainess from Criminal Case: Pacific Bay; both are women who stab their daughters to death out of anger at them for caring more for their career than for her. A difference is that Virginia felt remorse for her actions; Miranda did not.
- "No! I... I remember hurting someone, but she had NOTHING in common with my sweet little girl! That woman in the bus wouldn't even look up from her phone to greet me! It was like I was nothing to her! It wasn't enough that she broke her father's heart when she left for the big city, never bothering to call, or come back to visit... It wasn't enough that she didn't bother to come home when Hector got sick, despite my pleas! But she didn't even come to her own father's funeral! She left me to mourn him all alone! That woman I hurt... She wasn't my daughter. She'd become a monster!" (Virginia confessing to murdering Kelly, as well as her motivation)
