HILLSBORO, Ore- On July 30, 2026, Washington County Circuit Court Judge Brandon Thompson found Isidro Martinez-Ramirez, age 51, guilty of five counts of sexual abuse in the first degree and sodomy in the first degree (Jessica’s Law). Senior Deputy District Attorney Chris Lewman prosecuted this case.
 

The defendant sexually abused the minor victim in this case dozens of times over a three-year period when she was between seven and nine years old. In 2015, the victim reported this abuse to her mother and law enforcement. Her mother was initially uncooperative with the investigation, and police were unable to locate the defendant.
 

In December of 2021, the victim told a counselor about the abuse. The counselor notified the Forest Grove Police Department and the Oregon Department of Human Services. The victim also met with medical experts at CARES Northwest, where she provided additional details.
 

In 2021, the defendant was convicted of attempted sodomy in the first degree in a separate case after he provided a minor with methamphetamine and sexually assaulted the teen.
 

A sentencing hearing is scheduled for August 27, 2026. The defendant will remain in custody pending sentencing.

Christopher Lloyd Rydman Sentenced In Burglary Case (Photo) - 07/23/26

HILLSBORO, Ore- On July 21, 2026, Christopher Lloyd Rydman pleaded guilty to sexual abuse in the first degree, burglary in the first degree of an occupied dwelling, and private indecency and was sentenced to 10 years in prison by Judge Eric Butterfield. Senior Deputy District Attorney Andrew Freeman prosecuted this case.
 

On October 8, 2025, at about 10:45 p.m., the defendant entered an unlocked apartment in Beaverton, Oregon, that was home to a single mother and her children. The defendant then entered the primary bedroom and got into bed where the mother was sleeping. When the victim woke up, the defendant was lying next to her and touching her body. The woman ran from the room, recorded the defendant with her cell phone as he left the apartment. Her son called 9-1-1.

As officers investigated the first call, the defendant approached another home about a half mile away and loitered at the front door. This triggered a security camera and led to a second 9-1-1 call.
 

While officers were responding to the first two calls, the defendant entered another unlocked residence. He got into bed where a woman and her boyfriend were sleeping, but this time he was naked from the waist down. The couple woke up and were shocked to see the pants-less defendant in their bed. The man then used physical force to remove the defendant from the home. At that point, officers who were already in the area spotted the defendant in the street and arrested him.
 

The Washington County District Attorney’s Office commends the Beaverton Police Department for its work on this case, as well as the victims for the grace and courage they showed from the night of the incident through the court process.  

Mr. Rydman will be transferred to the Oregon Department of Corrections to serve his sentence. 

Armando Duran-Maya Sentenced To 15 Years In Prison In Domestic Violence Case (Photo) - 07/23/26

HILLSBORO, Ore - On July 21, 2026, Judge Erik Buchér sentenced Armando Duran-Maya to 15 years in prison. This sentence follows the defendant’s convictions by jury for unlawful use of a weapon, menacing constituting domestic violence, assault in the fourth degree constituting domestic violence, tampering with a witness (two counts), and extortion. This case was prosecuted by the specialized Domestic Violence team.
 

In this case, the defendant assaulted his girlfriend on multiple occasions spanning several days in December of 2024. The defendant threatened the victim with a machete during one of the assaults, and the victim feared for her life.
 

The victim reported these assaults to the police. However, she attempted to retract her report just two days later. Authorities learned that the defendant was contacting various family members and friends while in custody at the Washington County Jail and was urging them to pressure the victim to claim she filed a false report. The day he was released from custody, he located the victim and allegedly attacked her again. Rape charges for that incident are currently pending in Multnomah County.
 

During the sentencing hearing, the Judge said that this was one of the most egregious cases of domestic violence he had ever seen.
 

The defendant’s sentence was enhanced due to his criminal history. In the 1990s, the defendant raped a woman in her apartment in Portland. That case was solved in 2003 when the defendant’s DNA was entered into law enforcement databases after he participated in and was convicted of the attempted first-degree arson of an apartment building in Portland.
 

While released from custody pending trial in the earlier rape case, the defendant fled the state. He was ultimately located in the state of Washington in 2006 after a law enforcement pursuit. In 2007, he was convicted of rape in the first degree. After serving a lengthy prison sentence, he was released in 2016 and deported to Mexico. He then returned to the United States, and a community member reported that he was carrying a loaded firearm and threatening family members in Hillsboro in 2023. While back in the country, he never reported to Parole and Probation as required, and he failed to report as a sex offender.
 

The Washington County District Attorney’s Office commends the victim for her bravery throughout the legal process. This office also acknowledges the work of the Hillsboro Police Department, Portland Police Detectives, Washington County Parole and Probation, and the DA’s office Domestic Violence Investigators.
 

Mr. Duran-Maya will be transferred to the Oregon Department of Corrections to serve his sentence.

Jaycob Patrick Holten Sentenced In Domestic Violence Case (Photo) - 07/20/26

HILLSBORO, Ore- On July 20, 2026, Washington County Circuit Court Judge Hafez Daraee sentenced Jaycob Patrick Holten to 100 months in prison. This sentencing follows a criminal trial in which the defendant was convicted of assault in the second degree constituting domestic violence, assault in the fourth degree constituting domestic violence, and unauthorized use of a vehicle. Deputy District Attorney Katherine Miller prosecuted this case.

The victim and defendant were in an intimate relationship. On November 26, 2025, the defendant physically assaulted the victim, took her vehicle without permission, and threatened her with a knife. Fortunately, the victim’s roommate intervened, and the victim was able to escape the situation. The victim’s injuries were severe enough to require surgery.

Tigard police responded and spoke with the victim. They learned Mr. Holten was wanted for a felony warrant related to another instance of domestic violence. Investigators received information indicating the defendant was at his mother’s house and was possibly armed with a gun. Safety concerns prompted a large law enforcement response by members of the Tigard Police Department and Washington County Sheriff’s Office’s Tactical Negotiations Team. When officers arrived, they were able to contact the defendant, who agreed to exit the home peacefully.

The Washington County District Attorney’s Office commends the victim for her bravery in this case. This office also acknowledges the work of the Tigard Police Department and the detectives assigned to this case, as well as that of the Washington County Sheriff’s Office.

Mr. Holten will be transported to the Oregon Department of Corrections to serve his sentence.

Washington County Leaders Announce New Retail Theft Arrest Policy (Photo) - 07/16/26

HILLSBORO, Ore- The Washington County District Attorney’s Office, in partnership with all Washington County law enforcement agencies, is announcing a new presumptive arrest and booking policy for retail theft. For all misdemeanor and felony retail thefts, law enforcement will presumptively arrest and book suspects in the Washington County Jail when legally justified, rather than issuing a criminal citation to appear in court at a later date.

In a recent letter addressed to the business community, DA Kevin Barton joined Washington County law enforcement agencies to announce the presumptive arrest and booking policy and to urge retailers to report all crime to law enforcement and to review their vehicle removal policies. 
 

DA Barton and Washington County law enforcement agencies informed retailers that Washington County and its vibrant economy are targets for criminals. Case data shows that a significant percentage of retail theft in Washington County is committed by non-residents.  Reporting theft, arresting criminals, and removing their vehicles are steps that will help stop and deter crime.

“We have a zero-tolerance policy in our community for crime, including retail theft,” said Washington County DA Kevin Barton. “With this renewed focus on accountability and deterrence, we are sending a clear message to criminals who commit theft in our community: you will be arrested and prosecuted.”
 

Addressing retail theft is a priority in Washington County. In 2022, the DA’s Office created a countywide task force and obtained approximately $3 million in grant funds. Funding has been distributed to retail businesses to upgrade security systems and to law enforcement agencies to support retail theft enforcement missions, to purchase needed equipment, and to cover law enforcement overtime.

“Retail theft harms local businesses, employees, and the sense of safety we work hard to protect in Washington County,” said Washington County Sheriff Caprice Massey. “This new arrest and booking policy strengthens our ability to hold offenders accountable and supports the retailers who are vital to our community. When crimes are reported, we can respond quickly, take meaningful action, and help prevent future theft.”

The Organized Retail Crime Association of Oregon (ORCAOR) is a key partner in this effort. ORCAOR President Jeremy Girard knows the impact of retail theft on businesses and their employees.
 

“I commend the Washington County District Attorney’s Office and Washington County law enforcement partners for this initiative and for sending a clear message that organized retail crime and retail theft will not be tolerated in Washington County,” Girard said. “Strong partnerships and accountability are critical to protecting our retailers, employees, and communities. 
 

The new arrest and booking policies are already in effect.
