HILLSBORO, Ore.- On December 10, 2021, Washington County Circuit Court Judge Oscar Garcia sentenced Omar Nunez-Flores to 100 months in prison. On November 5, 2021, a jury found the defendant guilty of first-degree rape constituting domestic violence, first-degree burglary, and multiple counts of fourth-degree assault constituting domestic violence. Senior Deputy District Attorney Gina Skinner prosecuted the case against the defendant. 

On October 11, 2020, the defendant physically assaulted the victim in her home. The assault was witnessed by her minor child. She called police and he was arrested for causing an injury to her face by hitting her and interfering with her ability to call 9-1-1. The defendant was indicted for felony assault, harassment, and interfering with making a report. He was released with a No Contact Order with the victim and was awaiting trial when he committed the crimes that occurred on December 25, 2020.

Early in the morning of December 25, 2020, in violation of the No Contact Order, the defendant unlawfully entered the victim’s home through a broken window, physically assaulted her by kicking and biting her, and raped her. The victim’s teenage son heard the commotion and his mother’s cries for help. He called police and struggled with the defendant in an attempt to keep him in the apartment until officers could arrive. Unfortunately, Mr. Nunez-Flores fled the scene before officers could respond, leaving his shirt and hat behind. Law enforcement made multiple efforts to locate him, and he was ultimately arrested during a traffic stop months later. 

The Washington County District Attorney’s Office wishes to commend the victim and her son for reporting this abuse. This office also acknowledges the work of the Hillsboro Police Department on this case. 

The defendant will be transferred to the Oregon Department of Corrections to begin serving his sentence.  

HILLSBORO, Ore.- On December 14, 2021, Mark Allen Seidel pleaded guilty to first-degree invasion of personal privacy. Deputy District Attorneys Sara Loebner and Mitchell Diesko prosecuted the case before Washington County Circuit Court Judge Oscar Garcia.

On September 17, 2019, an instructor at a swim school in Beaverton, Oregon, reported she was changing in the staff changing area when she noticed a cell phone recording in one of the staff cubbies. When she examined the phone, she saw that it had been recording for the past 30 minutes and was oriented in a way to capture those changing their clothes.

Beaverton police responded and began investigating. Staff linked the phone to the defendant, who was employed as a maintenance worker at the school. Mr. Seidel admitted to recording but claimed he did so due to recent thefts in the staff changing room. He refused to show his phone to police and a search warrant was executed. Investigators with the Washington County Digital Forensics Laboratory eventually confirmed the phone was recording at the time it was discovered.

The Washington County District Attorney’s Office wishes to acknowledge the work of the Beaverton Police Department and the Washington County Digital Forensics Laboratory on this case.

A sentencing hearing is scheduled for February 11, 2022 at 8:30 a.m.

HILLSBORO, Ore.- On December 3, 2021, Douglas Edward Mulloy, age 78, pleaded guilty to first-degree online sexual corruption of a child, first-degree encouraging child sexual abuse, and luring a minor. Washington County Circuit Court Judge Brandon Thompson sentenced the defendant to 10 years in prison. Senior Deputy District Attorney Allison Brown prosecuted the case against Mr. Mulloy. 

The defendant, who was already a convicted sex offender prior to this case, began messaging someone whom he thought was a 15-year-old girl on a social media platform in May of 2021. That “girl” was actually Detective Chad Opitz of the Beaverton Police Department acting undercover.

Over the next several days, the defendant engaged in sexually explicit conversations and sent videos depicting child and adult pornography. He also tried to engage the “girl’s” 11-year-old sister in sexual activity as well. 

On June 2, 2021, the defendant agreed to meet the child at a park in Beaverton, Oregon. He was arrested upon his arrival. He admitted to police he was a registered sex offender and that he was there to meet a girl. He admitted to sending child pornography to her as well. Police found a cell phone, sex toys, condoms, and Viagra on the defendant. 

The Washington County District Attorney’s Office wishes to acknowledge the work of Detective Opitz and Beaverton police on this case. This case is another example of the importance of proactive police investigations into child sex abuse occurring online. The defendant will be transferred to the Oregon Department of Corrections to begin serving his sentence.

In January of 2021, the 10-year-old victim reported the defendant had been molesting her for a number of years. Tigard police and the Oregon Department of Human Services then launched an investigation.

“This child endured years of disparate abusive treatment at the hands of the defendant. We commend her for finding the strength to speak up and thank the supportive adults in her life who gave her the safe space to speak up in,” said DDA Meisel.

On October 10, 2019, the defendant approached a 12-year-old girl after he spotted her at a communal garbage disposal area of an apartment complex in Hillsboro, Oregon. The defendant told the girl that she was beautiful and asked for a hug. She refused and attempted to leave the area to return home. That’s when the defendant grabbed her from behind and pulled her towards a secluded area of the apartment complex. 

Fortunately, the girl was able to break free. She ran home and called police immediately. Hillsboro police responded and were able to identify the defendant as the suspect in the case. 

During the investigation of this case, additional victims came forward and reported historical sexual abuse by the defendant. The new information allowed this office to bring additional charges against Mr. Diaz-Guzman related to four additional victims.

This office also acknowledges the work of the Hillsboro Police Department and CARES Northwest.
