GARDEN GROVE, Calif. — A Southern California woman is behind bars after police say she poisoned her husband, cut off his penis and threw it in the garbage disposal because he “deserved it.”

At about 9 p.m. Monday, officers went to a home in Garden Grove, Calif., after a woman called 911 and reported a medical emergency, Garden Grove police Lt. Jeff Nightengale said.

Officers found a 51-year-old man tied to the bed and bleeding from his groin, he said. The man, who has not been identified, underwent emergency surgery at University of California Irvine Medical Center in Orange and was listed in serious condition, Nightengale said.

The 48-year-old woman, Catherine Kieu Becker, is accused of using an unknown poison or drug in her husband’s food to make him sleepy, Nightengale said. She then tied him to the bed and, as he woke up, she cut off his penis with a knife, Nightengale said.

She tossed the penis in the garbage disposal and turned it on, Nightengale said. She told responding officers that he “deserved it,” Nightengale said.

The victim told detectives that he believed there was something wrong with the food Becker prepared for him, Nightengale said.

Becker and the victim are going through a divorce, he said.

Becker was arrested on suspicion of aggravated mayhem, false imprisonment, assault with a deadly weapon, administering a drug with intent to commit a felony, poisoning and spousal abuse, Nightengale said.

The investigation is ongoing.
