HILLSBORO, Ore- On November 18, 2025, Antonio Arredondo Jr., age 39, pleaded guilty to seven charges of Rape in the First Degree, Sodomy in the First Degree, and Sex Abuse in the First Degree stemming from cases in both Oregon and Washington. The defendant stipulated to a 40-year prison sentence and is scheduled to be sentenced on March 16, 2026. Deputy District Attorney Rayney Meisel prosecuted the Washington County cases before Judge Brandon Thompson.
The defendant has been a registered sex offender since 2009, when he was convicted of molesting a child in Texas. He moved to Oregon shortly after his conviction in Texas, where his predatory behavior continued. By 2022, he had developed a pattern that granted him access to children.
The defendant would meet single mothers with daughters under the age of 10 years old, via an online dating site. Several of these children had some sort of disability. After initiating a relationship with them, he would begin sexually abusing the children. In some cases, he also became increasingly violent, both physically and sexually, towards the mothers. In one case, he repeatedly urged the mother to allow him to adopt her child and to give him power of attorney over the child, suggesting something would happen to the mother, and the child would need to be cared for. When the mother refused, the defendant would become outraged.
In May of 2022, one of the children reported to a school counselor that the defendant sexually abused the child. When the case was presented to a Washington County Grand Jury, the child’s mother disclosed to law enforcement that the defendant had been sexually and physically abusive to her as well.
The Tigard Police Department led the initial investigation. During the investigation, it was learned that another mother had reported abuse of her daughter by the defendant to the Washington County Sheriff’s Office. After presenting that second case to a Washington County Grand Jury, it was learned there may be other victims in the area.
On August 17, 2023, in collaboration with agencies across Oregon, investigators issued a media release to alert the public to the defendant’s actions and to seek additional victims. That information prompted victims in Polk County, Oregon, Clark County, Washington, and another victim, who now lives out of state, to contact law enforcement. This victim reported meeting the defendant before he sexually abused them.
After the defendant’s arrest in 2023, a joint effort was undertaken to resolve all of the defendant’s known cases. In late 2024, negotiations fell through. In February of 2025, the defendant was convicted of Sex Abuse in the First Degree in Polk County, Oregon, and began serving a mandatory minimum sentence of 75 months, pursuant to Oregon’s Measure 11 laws. Negotiations were reinitiated, and the defendant accepted the 40-year global offer with Washington County, Multnomah County, and Clark County, Washington.
“This resolution brings an end to this defendant’s predatory behavior and delivers long-overdue accountability,” said DDA Meisel. “Most importantly, it spares the victims the agony of reliving their trauma at trial and provides a measure of closure they have fought so bravely to obtain. Their courage in coming forward has been nothing short of extraordinary.
During the course of the investigation, detectives spoke with multiple women who reported similar behavior by the defendant, some of whom did not want to participate in the prosecution. Investigators fear there could be additional victims. Anyone with information related to the defendant is urged to call their local law enforcement agency.
The Washington County District Attorney’s Office commends all victims for their bravery in reporting the defendant. This office also acknowledges the work of the Tigard Police Department, the Washington County Sheriff’s Office, the Portland Police Bureau, the City of Dallas Police, and law enforcement agencies in the State of Washington.
