Kerry Napoli

Kerry Napoli Is the main villainess from "The Fight in the Fixer," episode 11.15 of Bones.

She was played by Alyssa Diaz.

Kerry Napoli is the assistant to Frank Kwiatowski, a private investigator who specialized in "solving" the problems of his high-profile clients. She was also Frank's mistress, though it was not revealed when their affair began. On one job, Frank and Kerry helped an Omani prince beat a drunk driving charge in New Jersey, and during the job, they robbed the prince of $2 million, which Kerry put in a safe deposit box.

After the affair was revealed during her interrogation, Kerry claimed that she and Frank were in love with each other and they were going to use the money to leave the country together. As revealed later on, however, Kerry was actually a greedy villainess, and she took the opportunity to kill Frank in his office, doing so by bashing his head on to his sink. After the murder, Kerry covered her tracks by blackmailing her clients to give her an alibi, which had her being in Atlanta at the time of the murder.

Booth revealed Kerry as the murderer during his interrogation of her, as he told her that she was a private investigator just like Frank, and she didn't believe in "happily ever after." Kerry was also informed by Booth that one of her clients changed his tune after Booth reassured him that Kerry wouldn't threaten him anymore. Booth later arrested Kerry for Frank's murder.
