Aiden was a Brooklyn native who had the ability to adapt to new situations very quickly and had a love and drive for her job.
She was dismissed from the team after becoming obsessed with a rape case concerning her friend Regina Bowen.
Aiden pulled the evidence gathered from the first rape. She broke the seal on the packet containing the hair and contemplated planting it at the alleged scene. Though Aiden did not actually plant the hair, the fact that she had broken the seal on the evidence packet earned her a severe reprimand from her supervisor, Detective Mac Taylor. Intent on preserving the integrity of the crime lab, Mac felt that he had no other option than to fire Aiden. Aiden understood Mac's decision, even agreeing with it, because she admitted to not knowing if she would resist similar temptation in the future.
After her dismissal from the crime lab, Aiden was apparently working on getting her private investigator's license while continuing to search for evidence that would conclusively tie Pratt to the Regina Bowen case. Aiden was lured, ambushed, and brutally murdered by him, her body incinerated inside a stolen car. However, knowing that her time was drawing short, she left behind critical evidence that she knew would help her former colleagues to close in on Pratt and finally see him arrested.
Aiden's murder devastated Mac and the rest of the team, particularly Detective Danny Messer. Though she at one time had joked that she was way out of his league, Aiden and Danny shared a very close relationship.
