PORTLAND, Ore. (KOIN) – A Portland father who is accused of allowing drug use in his home, leading to the overdose death of a 15-year-old girl in 2023, pleaded guilty to two charges on Wednesday.

According to court documents, 52-year-old Hooman Tony Rahnamoon pleaded guilty to frequenting a place where controlled substances are used and endangering the welfare of a minor.

The case goes back to February of 2023, when Franklin High School freshman Lauren Dominguez died of a fentanyl overdose. Dominguez was in the home of a 17-year-old boy, Rahnamoon’s son, according to court documents.

Rahnamoon was accused of allowing the teens to do drugs after seeing it take place and not intervening.

Lauren’s parents, Tracy and Marc Dominguez, previously said that the last time they saw Rahnamoon was on the morning of Feb. 18, 2023, after they found out Lauren was missing from school. Lauren’s sister found out through social media sleuthing that she had snuck out to visit Rahnamoon’s son the night before.

“The homeowner comes down the driveway, lets us know that our 15-year-old daughter is upstairs and she’s not breathing. She was using drugs with his son, is what he said,” Tracy said.

Prosecutors said Lauren and the son had previously met up to use drugs the night before, with Narcan and drug paraphernalia found after her death.

Court documents show Rahnamoon later admitted “about 4-5 days, at most a week, before she passed, he had observed his son,” and Lauren using drugs at his home.

Dominguez’s parents told KOIN 6 News in February that they believe their daughter was caught in a perfect storm between the end of the COVID-19 pandemic and the impacts of Measure 110, the Oregon law that temporarily removed criminal penalties for people caught with small amounts of hard drugs. That state legislature later reintroduced criminal penalties with House Bill 4002 in 2024.

During his arraignment in February, Rahnamoon pleaded not guilty to three misdemeanor charges — frequenting a place where controlled substances are used and two counts of endangering the welfare of a minor — and apologized repeatedly to Lauren’s parents in court.

Now, as part of a plea deal entered Wednesday, the state recommends dismissing all of the charges at the time of Rahnamoon’s sentencing if over the next 18 months he completes a drug and alcohol evaluation and treatment, writes an apology letter to the family of Lauren Dominguez, does not allow minors into his home, refrains from alcohol and drug use and does not allow drugs or alcohol into his home.

Rahnamoon’s sentencing is scheduled for 2027.

An attorney representing Rahnamoon declined to comment on the case.

The parents of Lauren Dominguez were initially told the case did not involve a “ticketable” offense. However, with a new district attorney in office, the Dominguez family said they had hope for accountability.

Speaking with members of the media on Wednesday, Multnomah County District Attorney Nathan Vasquez said, “I turned to Senior Deputy DA JR Ujifusa and said we have to take action. We have to do better as a community, and we need to make sure this individual is held accountable. And that’s what today is about.”

“I am so proud of my office for standing up for this family,” Vasquez continued. “And I will tell you, I am honored to have met and worked with the Dominguez family. They are incredible parents, and they have worked so hard to honor their daughter’s memory and to help this community get better.”

In a statement shared with KOIN 6 News, Vasquez described the “unique” nature of the plea deal.

“I’d say it’s pretty unique and it is a product of this family, the Dominguez family,” Vasquez said. “This was never about being vindictive. It was about holding this defendant accountable and about seeking better from our community and above all, making sure this doesn’t happen again in that home where children are in danger.”
