Washington Co. District Attorney's Office

HILLSBORO, Ore.- On December 29, 2021, 23-year-old Devanne Joshua Branderhorst pleaded guilty to compelling prostitution and second degree sexual abuse. On January 6, 2022, Washington County Circuit Court Judge Kathleen Proctor sentenced the defendant to a total of 70 months in prison. Senior Deputy District Attorney Allison Brown prosecuted the case against Mr. Branderhorst. 

The case involved sexual assault and efforts to facilitate the prostitution of two victims, ages 17 and 18. Police first learned of the defendant’s crimes in December of 2019, after they were called to a disturbance at a house in Washington County, Oregon.  The defendant was at the residence with both victims and was providing them alcohol and prescription medication. He sexually assaulted the 18-year-old victim while she was intoxicated. 

As part of the investigation, police learned the defendant was causing the 17-year-old victim to engage in prostitution. These acts of prostitution went on for months and were arranged using the social media website, Seeking Arrangement. This website is often associated with illegal sexual activity. Police discovered text messages showing the defendant directing the victim’s acts of prostitution. He also had a sexual relationship with the victim. He attempted to cause the 18-year-old to engage in prostitution as well but was unsuccessful.

Detectives interviewed the defendant. He initially denied the allegations involving both victims but later admitted he did establish accounts on Seeking Arrangement for two victims.

Judge Proctor also ordered the defendant to undergo post-prison supervision for three years following his release and required him to register as a sex offender. Mr. Branderhorst will be transferred to the Oregon Department of Corrections to begin serving his sentence. 

In addition to this case, sheriff’s deputies also arrested Robert Kiyoshi Sunamoto, age 75, after he used the same website to contact one of the victims for sex. Detectives determined he met the 17-year-old victim, took her back to his home, and paid her for sex. In July of 2021, Mr. Sunamoto pleaded guilty to commercial sexual exploitation and was sentenced to two years of probation.

This case is an important reminder of the dangers present online for children.
