Utah Sentences Abuser for Girlfriend’s Suicide Death
A Utah judge sentenced Caleb Aidan Rees to up to 20 years in prison on July 17, 2026, for the 2021 death of his girlfriend Rena Nguyen, a 20-year-old Brigham Young University student. Rees did not pull a trigger. He left a loaded handgun in a room with Nguyen while she was in crisis, yelled at her as she cried, and walked away.
Nguyen’s family spent more than two years pushing Utah County prosecutors to charge Rees before he finally pleaded guilty in April 2026 to a third-degree felony count of manslaughter, along with drug and weapons charges. Judge Sean Petersen of the 4th District Court in Provo ordered four consecutive terms of up to five years each.
“Nothing short of horrific.”

Why This Case Could Change How Domestic Violence Is Prosecuted
Nguyen’s attorney Richard Lambert says this is the first case he knows of in the United States in which a domestic abuser was criminally convicted for driving a partner to suicide. The legal precedent is rare even internationally. In Scotland, a man is serving eight years after prosecutors argued his wife’s suicide followed sustained physical and emotional abuse during their 18-month marriage.
Prosecutors played a recording Nguyen had secretly made in Orem on October 21, 2021, documenting her interactions with Rees in the hours before her death. The recording became central evidence in a case that nearly never happened.
The Nguyens hired private attorneys and brought in an expert witness to persuade authorities to act. Most families in similar situations do not have those resources. That access gap is the policy problem here.
“We must use every tool under the law to deter anyone who even considers harming another person.”

What Prosecutors and Lawmakers Can Do Now
The Nguyens are now asking authorities in Utah and other states to reopen closed cases where a partner’s suicide followed documented abuse. The conviction shows that manslaughter statutes can reach coercive conduct that stops short of physical killing. Whether prosecutors use that tool depends on training, political will, and resources.
Domestic violence coalitions have long documented that coercive control, including emotional abuse and manufactured access to lethal means, is a predictable precursor to a victim’s death. The criminal justice system has historically treated those deaths as non-prosecutable. This conviction challenges that assumption.

What You Can Do Now
-
Call your Utah state legislators through the Utah Legislature’s main line at (801) 538-1029 and urge them to direct the Utah Commission on Criminal and Juvenile Justice to study coercive control homicide cases closed without charges. Name Rena Nguyen and ask for a formal case review process.
-
Contact the Utah Attorney General’s office at (801) 366-0260 and ask them to issue guidance to county prosecutors on applying manslaughter statutes to coercive-control suicide deaths. The Nguyen case is now on record as a prosecutable model.
-
Reach the Utah Domestic Violence Coalition’s 24-hour hotline at 1-800-897-5465 if you are supporting a survivor of coercive control, or share the number directly with someone who needs it. Coercive control often escalates before families recognize it as abuse.
-
Ask your U.S. senators to strengthen the Violence Against Women Act’s coercive control provisions by calling the Capitol switchboard at (202) 224-3121. The reauthorization cycle creates a window to add prosecutorial training grants specifically for coercive-control homicide cases.
