HILLSBORO, Ore.- On June 5, 2020 a Washington County grand jury indicted Washington County Jail Deputy Rian Alden on one count of Official Misconduct in the First Degree concerning a use of force incident that occurred in the jail in 2018.

This incident was investigated by the Multnomah County Sheriff’s Office and the Oregon State Police in 2018.  At that time and based on the known evidence, charges were not filed. New evidence recently became known which prompted a re-opening of the investigation and this indictment.

Pursuant to ORPC 3.6, the Washington County District Attorney’s Office cannot comment further on this case as it has not yet been adjudicated.

HILLSBORO, Ore.- On May 28, 2020, a Washington County jury found Jose Luis Nava-Diaz guilty of unlawful delivery of methamphetamine and unlawful possession of methamphetamine. On June 1, 2020, Judge Eric Butterfield sentenced the defendant to 115 months in prison. Deputy District Attorney Jason Ring prosecuted the case against Mr. Nava-Diaz.

On January 23, 2020, the defendant was stopped by deputies with the Washington County Sheriff’s Office as he exited a vehicle at the Elmonica MAX Station in Beaverton, Oregon. Investigators with the Westside Interagency Narcotics Team (WIN) identified the defendant as being involved in the illegal distribution of narcotics. Deputies located approximately six pounds of methamphetamine and drug paraphernalia during their search. The defendant was then taken into custody.

Investigators subsequently obtained a search warrant for the defendant’s home. There they found an additional four ounces of methamphetamine.

The Washington County District Attorney’s Office acknowledges the work of the WIN team and the Washington County Sheriff’s Office on this case.

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

HILLSBORO, Ore.- On June 3, 2020, Kaliq Michael Mansor pleaded guilty to manslaughter in the first degree, assault in the first degree, and criminal mistreatment in the first degree. Judge Oscar Garcia then sentenced the defendant to 27 ½ years in prison. District Attorney Kevin Barton and Senior Deputy District Attorney John Gerhard prosecuted the case against Mr. Mansor.

In 2012, the defendant was convicted on multiple charges and sentenced to life in prison with a minimum of 27 years for his role in the death of his infant son. In 2018, the Oregon Supreme Court overturned that conviction citing concerns with a search warrant executed on the defendant’s computer. That decision led to this second trial which was scheduled to begin this fall until the defendant opted to plead guilty to the above charges.

On June 12, 2011, Mr. Mansor called 9-1-1 to report his infant child was not breathing. The boy was rushed to the hospital but was declared brain dead the following day. Subsequent medical evaluation on that child and another child under the defendant’s care uncovered a history of abuse.

Mr. Mansor told investigators that he was home alone with the children when one of them began to choke while the defendant was feeding him. Mr. Mansor said he then shook the child and smacked his back in an effort to clear his breathing way. He reported the child’s breathing became very labored but waited an additional 15 minutes before calling for help.

Investigators obtained a search warrant for the defendant’s computer. Internet search history unveiled queries including, “how do I stop abusing my baby” and “how do I keep from losing my temper.” After this initial search warrant was ultimately deemed insufficient, investigators sought and obtained a second search warrant for the device in preparation for a new trial.

The Washington County District Attorney’s Office acknowledges the Washington County Sheriff’s Office including Detective Robert Rookhuyzen, CARES Northwest and medical personnel for their work on this case.

In addition to his prison sentence, the defendant will also undergo more than twelve years of post-prison supervision upon his release. The defendant will be transferred to the Oregon Department of Corrections to begin serving his sentence.

If you know of a child suffering abuse, report it immediately by calling 9-1-1. You can also report your concerns to the Oregon Child Abuse Hotline by calling 1-855-503-SAFE.

The victim’s mother also provided this statement.

HILLSBORO, Ore.- The following is a statement from Washington County District Attorney Kevin Barton:

Like many of you I am deeply disturbed and saddened by examples of racism and bias that are occurring in our nation.  In just the past few weeks we have heard about a man shot and killed while jogging in Georgia, a man threatened in New York’s Central Park while bird watching, and a man who died after being held with a knee to his neck in Minnesota.  While these tragic examples may be on the national news, we must remember that it is our local obligation to be vigilant against all forms of hate or bias.

As District Attorney for Washington County, Oregon’s fastest growing and most diverse county, I am proud to work with our partners in law enforcement to protect and serve all members of our community.  An important example of the outreach we do is our annual “Building Bridges of Understanding” event involving public safety agencies and our diverse community members and organizations.  I encourage anyone who would like to join the fight against hate and bias to consider attending this year’s event in October.  An essential aspect of being safe is feeling safe and our mission in the DA’s Office is to ensure everyone in our community, regardless of skin color or ethnicity, feels safe in Washington County.

This website has additional details on the Building Bridges of Understanding program. You can also view this video of last year’s event.

HILLSBORO, Ore.- On May 18, 2020, a Washington County jury found Manuel Alfonzo De Leon Say guilty of two counts of first-degree unlawful sexual penetration and four counts of first-degree sexual abuse. On May 26, 2020, Judge Janelle Wipper sentenced the defendant to 25 years in prison. He was also ordered to register as a sex offender. Deputy District Attorney Chris Lewman prosecuted the case.

In August of 2018, a witness observed the defendant sexually abusing the young victim at a business in Hillsboro, Oregon. The witness immediately removed the child from the area and reported the incident to Hillsboro Police.

Detectives began to investigate, and the child was interviewed by medical experts at CARES Northwest. The victim described inappropriate touching and conduct by the defendant at both the business and a residence.

The Washington County District Attorney’s Office acknowledges the investigative work of Hillsboro Police Detective Megan Townsend on this case. This office also thanks CARES Northwest for their assistance.

HILLSBORO, Ore.- On May 7, 2020, Austin Michael House pleaded guilty to four counts of attempted using a child in display of sexually explicit conduct and first-degree encouraging child sexual abuse. On June 11, 2020, Mr. House was sentenced to 280 months in prison. Senior Deputy District Attorney Andy Pulver prosecuted the case before Judge Ted Sims.

In October of 2017, the defendant, aged 26 at the time, was caught engaging in sexually explicit conduct online with a 15-year-old girl living outside of Oregon. The victim’s grandmother searched the defendant’s social media accounts and determined he lived in Beaverton, Oregon. She then immediately contacted the Washington County Sheriff’s Office which launched an investigation into the incident.

Detectives obtained search warrants for Mr. House’s home and multiple electronic devices. They found evidence of similar crimes involving three additional minors, all living outside Oregon. Investigators also found multiple images and videos depicting children engaged in sexually explicit conduct.

Over the course of two law enforcement interviews, the defendant admitted to detectives that he was aware of the victims’ ages and admitted to engaging in sexually explicit conversations with them via social media and other digital platforms.

The Washington County District Attorney’s Office credits the victim’s family for making the initial report, and the Washington County Sheriff’s Office for their investigative work on this case. This office also acknowledges Detective Tim Mateski for his detailed investigation and continuing efforts to identify the defendant’s additional victims.
