HILLSBORO, Ore.- On January 31, 2020, a Washington County jury convicted Mauricio Ambriz-Arguello of three counts of first-degree rape, second-degree sodomy and four counts of first-degree sex abuse. Deputy District Attorney Chris Lewman prosecuted the case against the defendant in Judge Charles Bailey’s courtroom.

The abuse began when the victim was approximately six-years-old and continued into her teenage years. The victim reported the abuse to a close family member at least once throughout this time but was pressured to recant her allegations. The abuse continued for several more years after that initial disclosure.

During this time, the victim became suicidal and attempted to take her own life. When a separate family member learned of this, she became concerned for the victim’s safety. The victim then disclosed the abuse she suffered, and the family member encouraged her to speak to a school counselor.

The victim disclosed details of the abuse to a school counselor. That counselor immediately notified police and officials launched an investigation. The victim was interviewed by experts at CARES Northwest where she gave additional details of what she endured. Mr. Ambriz-Arguello was also interviewed by Beaverton Police with the assistance of an interpreter. He admitted to inappropriate touching but denied the bulk of the allegations against him.

The Washington County District Attorney’s Office would like to acknowledge the work of Beaverton Police, Officer Mark Kirlin and CARES Northwest for their work on this case. This office also commends the victim for showing the courage to report the abuse she suffered.

A sentencing hearing is set for February 12, 2020 at 8:30 a.m. The defendant will remain in custody until that time.

HILLSBORO, Ore.- On January 29th, 2020, Anna Louise Foster-Wylie pleaded guilty to felony driving under the influence of intoxicants and was sentenced to 30 months in prison by Judge Eric Butterfield. Deputy District Attorney Bryce Bissinger prosecuted the case against Ms. Foster-Wylie. This is the defendant’s ninth conviction for driving under the influence.

On September 19, 2019, the defendant was spotted by a concerned citizen along East Main Street near Southeast 3rd Avenue in Hillsboro, Oregon. The citizen called police to report the defendant was sitting in her car as it idled. The caller told police the defendant was yelling and slurring her words.

Officer Marco Ramirez of the Hillsboro Police Department responded to the scene. Officer Ramirez found the defendant in her car with the engine running. The officer noted the defendant presented multiple signs of intoxication including slurred speech, a lack of focus, incoherent statements and a strong odor of alcohol on her breath. She refused field sobriety tests and was taken to an area hospital when she became combative.

Officer Ramirez obtained a warrant to test the defendant’s blood. Those results later showed a blood alcohol content of 0.217 in blood samples taken three hours after she was first arrested.

The Washington County District Attorney’s Office would like to acknowledge the work of Officer Ramirez and Hillsboro Police in protecting public safety by responding to the scene quickly before the defendant could endanger others. This office also salutes the concerned citizen for calling police to make the initial report.

Judge Butterfield also ordered Ms. Foster-Wylie to undergo three years of post-prison supervision upon her release. She will be transferred to the Oregon Department of Corrections to begin serving her sentence.

HILLSBORO, Ore.- On January 17, 2020, a jury found Cupertino Juarez-Hernandez guilty of 25 counts in relation to child sex abuse. Those convictions include multiple counts of first-degree sodomy, first-degree rape and using a child in display of sexually explicit conduct. On January 23, 2020, Mr. Juarez-Hernandez was sentenced to 55 years in prison by Judge Charles Bailey. Deputy District Attorney Chris Lewman prosecuted the case against the defendant.

Deputy District Attorney Lewman proved in court that the defendant sexually abused four children for many years. The abuse began when the victims were young children and continued into their teenage years.

The Washington County District Attorney’s Office would like to acknowledge the investigative work of Detective Mark Povolny of the Washington County Sheriff’s Office. This office also commends the work of CARES Northwest and the Oregon Department of Human Services. Finally, this prosecution would not have been possible without the bravery shown by the victim in reporting the abuse to law enforcement.

The investigation revealed that two other adults known to the children also sexually abused them during the same time frame. The two other defendants in this case are set for trial in April and June.

Mr. Juarez-Hernandez will be transferred to the Oregon Department of Corrections to begin serving his sentence.

HILLSBORO, Ore.- On January 15, 2020, Judge Eric Butterfield found Aronson Bellegarde guilty of two counts of third-degree assault, two counts of failure to perform the duties of a driver to injured persons, driving under the influence of intoxicants, reckless driving, two counts of recklessly endangering another person, second-degree criminal mischief and second-degree disorderly conduct in a bench trial. Deputy District Attorney Matt Wise prosecuted the case against Mr. Bellegarde.

On March 16, 2019, Mr. Bellegarde smoked a large amount of highly concentrated marijuana oil and got behind the wheel of his vehicle. He drove to the intersection of SW Hall Boulevard and SW Scholls Ferry Road in Beaverton, Oregon. He then abandoned his car in the middle of the street, jumped onto the hood of another vehicle and ran into a nearby grocery store.

The defendant then walked out of the grocery store, got back into his vehicle and started driving again. He nearly caused two head-on collisions as he drove through the Washington Square Mall area before he careened down a grass embankment leading to Highway 217. He then crashed into two vehicles driving northbound on the highway. An infant and young child were passengers in one of those vehicles. Fortunately, they were not hurt.

Following those collisions, the defendant stripped naked, rolled under various vehicles on Highway 217, jumped over the center median and took off running through the southbound lanes. Beaverton Police arrived and attempted to arrest Mr. Bellegarde. He again took off running but was arrested a short time later.

The defendant admitted to smoking a marijuana vape pen prior to the ordeal. A warrant was executed for his blood and urine. Those results showed high concentrations of THC in his system.

The Washington County District Attorney’s Office would like to acknowledge the work of Beaverton and Tigard police officers in apprehending the suspect quickly so that no other drivers would be put at risk.

A sentencing hearing will be held on January 28, 2020 at 1:00 p.m.

HILLSBORO, Ore.- On January 13, 2020, a Washington County jury found Sebastian Sylvester Meighan guilty of two counts of first-degree rape, second-degree rape and four counts of first-degree sex abuse.

Investigators learned the sexual abuse began when the victim was a young child and that it continued for at least eight years. The abuse was wide-ranging in nature.

During the same time period, the victim learned the defendant was going to become a father to a baby girl.

The victim alerted a school counselor, who notified the Oregon Department of Human Services. The Washington County Sheriff’s Office launched an investigation, ultimately leading to the arrest of Mr. Meighan.

The Washington County District Attorney’s Office would like to acknowledge the incredible bravery of the victim in reporting the abuse. This office also thanks Detective Chuck Anderson of the Washington County Sheriff’s Office, CARES Northwest and the Oregon Department of Human Services for their work on this case.
