A 49-year-old man from Portland, Konstantin Y. Svidenko, is now facing a total of 17 charges, including first-degree rape, kidnapping, and attempted sexual abuse. Detectives from the Portland Police Sex Crimes Unit are urgently seeking information from the public about any other potential crimes committed by the offender.
Over the course of several months, four women came forward to report incidents of sexual assault within Svidenko’s apartment. The Portland Police Sex Crimes Unit, then launched investigations into these cases.
The situation escalated on September 4, 2023, when North Precinct officers responded to a report of a man making threats to a woman in the 4200 block of Northeast 122nd Avenue. It was identified that the suspect in question was none other than Svidenko. Despite an exhaustive search lasting over an hour, officers were unable to apprehend him initially.
In the late hours of September 5, 2023, at approximately 12:20 a.m., a K9 Sergeant and K9 officer located and successfully arrested Svidenko in the 1110 block of Northeast 122nd Avenue. He was subsequently booked into the Multnomah County Detention Center to face the mounting charges against him.
Despite this arrest, detectives remain concerned that Svidenko may have victimized other women. As the investigation unfolds, the Portland Police Bureau (PPB) has released a photograph of Svidenko, along with a description. He is described as a white male, 5’10” in height, weighing 175 lbs, and speaking with a heavy Russian accent. Svidenko is known to frequently ride a bicycle and resides in an apartment near Northeast 122nd Avenue and Northeast Multnomah Street.
The Multnomah County District Attorney’s office presented the cases to a Grand Jury, resulting in the indictment of Svidenko on multiple severe charges. These charges include Rape in the First Degree, Attempted Rape in the First Degree (2 counts), Sexual Abuse in the First Degree, Attempted Sexual Abuse in the First Degree (2 counts), Kidnapping in the First Degree (8 counts), Strangulation (2 counts), and Assault in the Fourth Degree.
The PPB is urging anyone with information related to this case or potential additional victims to come forward and assist in this ongoing investigation. Your cooperation could be crucial in ensuring justice prevails and the safety of the community is maintained. Please contact the Portland Police Sex Crimes Unit with any information that may aid in this case.
A criminal complaint is only an accusation of a crime, and a suspect is presumed innocent until proven guilty in a court of law.
