Catherine Kieu: Attack, Trial, Sentence, and Appeal

Catherine Kieu is the Garden Grove, California woman serving seven years to life in state prison for drugging her estranged husband, tying him to a bed, and severing his penis with a kitchen knife on July 11, 2011. A jury convicted her of torture and aggravated mayhem in April 2013. She remains incarcerated and was most recently denied parole in September 2025.¹

What Happened on July 11, 2011

Kieu, then a real estate agent, laced a meal with a sleep aid and served it to her 51-year-old estranged husband at the Garden Grove home they still shared. After he lost consciousness, she tied his arms and legs to the bed with rope and removed his clothing. When he came to, she used a 10-inch kitchen knife to cut off his penis, then dropped the severed organ into the garbage disposal and turned it on.²

Kieu herself called 911 and reported a medical emergency. Officers who arrived found the victim still tied to the bed and bleeding heavily. Kieu told them her husband “deserved it.”³ He was taken to UC Irvine Medical Center for emergency surgery. Detectives collected the prepared food and the knife as evidence.⁴

The Marriage and the Divorce

The victim was identified in court only by his first name, Glen, because of the sexual nature of the crime. The couple had no children. About two months before the attack, Glen had filed for divorce, though the pair continued to live together in his Garden Grove home.⁵ Prosecutors said the attack followed an argument tied to the divorce and that Kieu refused to accept Glen’s decision to end the marriage.

The Charges and the Trial

A grand jury indicted Kieu in January 2012 on one felony count of torture, one count of aggravated mayhem, and a sentencing enhancement for personal use of a knife.⁶ The case went to trial before Superior Court Judge Richard F. Toohey in Santa Ana, with Deputy District Attorney John Christl prosecuting and Deputy Public Defender Frank Bittar for the defense.

Christl told the jury that the attack was driven by “vengeance, vanity and jealousy” and that Kieu had “carefully planned” it by drugging Glen first.⁷ He argued she “took away everything but his life that day” and “permanently deprived him of his manhood for the rest of his life.”⁵ Glen testified at the trial, telling jurors, “She murdered me that night,” and, “I will never have a sex life again.”⁸

Bittar built the defense around Kieu’s mental health and history. He told the jury she had endured childhood trauma in war-torn Vietnam, including being raped by an older brother after her mother died when she was five, and that untreated trauma, cultural factors, and an abusive marriage in which Glen “constantly demanded sex in ways that caused her pain” led to a “break from reality” the night of the attack.⁹ He described her as a “shattered woman” while acknowledging that “no one could condone what the victim went through.”¹⁰ The defense argued post-traumatic stress disorder prevented Kieu from forming the intent required for the torture and aggravated mayhem charges.¹¹

On April 29, 2013, after about four hours of deliberation, a jury of eight women and four men convicted Kieu on both counts and found the knife enhancement true. She sat motionless as the verdict was read.⁵

Sentence

On June 28, 2013, Judge Toohey sentenced Kieu to seven years to life in prison, which included the aggravated mayhem and torture convictions plus two additional years for the knife enhancement. He denied a defense request for probation and called the attack “calculated and cold as many first-degree murder cases.”¹²

Glen addressed the court, telling the judge, “This was a cruel and calculated violation of a person’s body and mind” and that Kieu “tore off my identity as a man.” He added, “I never saw it coming. She has betrayed my trust in people. My right to the pursuit of happiness has been robbed.”¹³

What Happened to the Victim

Because the severed organ was destroyed in the garbage disposal, reattachment was impossible. Dr. Joel Gelman, director of UC Irvine’s Center for Reconstructive Urology, said that any reconstruction would not produce a “native, normal penis,” and that a full phalloplasty, costing upwards of $100,000, would not restore full sensation and would require an inflatable implant to achieve an erection.¹⁴ Later reporting indicated that reconstructive surgery was ultimately unsuccessful.¹²

The Appeal

Kieu appealed, arguing there was insufficient evidence she intended to cause cruel or extreme pain and suffering, which is required for a torture conviction. In July 2014, a three-justice panel of California’s Fourth District Court of Appeal rejected that argument, finding that her own statement to officers that Glen “deserved” the injury established the intent to inflict pain.¹⁵ The panel did grant her 108 days of good-conduct credit for time spent awaiting trial, which moved her earliest parole eligibility date up by roughly three and a half months.

Where Catherine Kieu Is Now

The indeterminate seven-to-life sentence made Kieu eligible for parole hearings beginning around 2019 or 2020 once custody credits were applied. At her most recent suitability hearing on September 3, 2025, the California Board of Parole Hearings denied parole for three years, meaning she is not eligible for another hearing until approximately 2028.¹ She remains in the custody of the California Department of Corrections and Rehabilitation under CDCR number WE7020.¹⁶
