A Garden Grove, Calif., woman convicted of cutting off her ex-husband's penis with a 10-inch kitchen knife, then throwing it in a garbage disposal, was sentenced Friday to life in prison with the possibility of parole in seven years.

Catherine Kieu, 50, was convicted in the July 2011 attack in which prosecutors said she drugged her ex-husband's meal with a sleep aid, then severed his penis with a knife after tying him to a bed. She then mutilated the penis by throwing it in the garbage disposal.

The victim was in court for Friday's sentencing.

"I'm hoping this will be the last time I ever have to see her," he said. "I felt some relief, and it was a very sad day for me."
