A Tempe, Ariz., woman who stabbed her lover during sex to drink his blood has been sentenced to 10 years in prison.
Tiffany Sutton -- who pleaded guilty in August to two counts of aggravated assault stemming from the February incident, and a previous violent encounter with a police officer during a trespassing arrest -- expressed remorse Tuesday before she was sentenced, The East Valley (Ariz.) Tribune reported Wednesday.
"I'm really sorry that all this went on," Sutton told Maricopa County Superior Court Judge David Udall. "I never meant to hurt anyone."
A police report said Sutton and her victim, Robert McDaniel, were drunk and high on drugs when he agreed to be tied up during sex. McDaniel later told police he became frightened and asked to be untied when Sutton attacked him with a knife.
She sliced his leg, punctured his arm, shoulder and back, and cut his neck and stomach before he managed to escape, court records say. She then chased him with a pickax until a friend intervened and called 911.
Sutton's mother said her daughter has struggled with mental health issues for most of her life and prison health records state that Sutton thought she was a vampire for several weeks after her arrest.
