Police arrested 31-year old Jacqueline Ades after finding her in a Paradise Valley man's bathtub.
According to investigators, she had met the guy online about a year ago but she won't leave him alone.
Court documents say Ades sent the victim about 500 messages a day, which included disturbing ones like "I want to wear your body parts" and "bathe in your blood."
Officers say they found a butcher knife in her car when she was most recently arrested on charges of threatening, stalking and harassment.
She's now in jail with no bond.
