SANTA ANA, Calif. (KTLA) — Opening statements began Wednesday in the trial of an Orange County woman accused of cutting off her husband’s penis and putting it in the garbage disposal.

Prosecutors say 50-year-old Catherine Kieu spiked her 60-year-old husband’s dinner with drugs on July 11 of 2011.

Kieu then allegedly tied him to his bed with nylon ropes and cut off his penis with a 10-inch kitchen knife.

She then threw it in the garbage disposal and turned the disposal on, mutilating the organ, according to prosecutors.

Kieu was the one who called 911, and authorities say she told responding officers that her husband “deserved it.”

Her husband was treated and released from UC Irvine Medical Center, but doctors were unable to re-attach his penis.

Police say they believe Kieu was upset at her husband for filing for divorce after 16 months of marriage.

The pair was married on Dec. 29, 2009, and Kieu’s husband, identified only as Glen B, filed for divorce in May 2011.

They continued living together in a condominium complex in Garden Grove.

On the night of the alleged attack, the couple had reportedly argued over the possibility of a friends staying at their condo at a later date.

Defense attorneys Wednesday accused Glen B of being a sexual fiend who forced Kieu to have sex with him.

Her attorneys also pointed out that Kieu’s mom died when she was 5-years-old and alleged Kieu had been raped when she was 6-years-old.

Kieu was indicted on one felony count of torture and one felony count of aggravated mayhem.

She also faces a sentencing enhancement for personal use of a knife.

If convicted, Kieu could get life in prison without the possibility of parole.

Kieu has pleaded not guilty to the charges against her.
