Clackamas County deputies arrested 24-year-old Jacob Todd Koser on Thursday, Jan. 29, on multiple sexual-assault and related charges, and investigators say they are now looking for other possible victims. Deputies also released a booking photo in hopes that anyone who recognizes Koser, or believes they had contact with him, will come forward.
According to KGW, the Clackamas County Sheriff’s Office booked Koser on counts that include first-degree rape, strangulation, menacing, fourth-degree assault, unlawful delivery of marijuana, and providing liquor to a person under 21 or to an intoxicated person. KGW reported that Koser, 24, was arrested in Oak Grove on Jan. 29 and is being held at the Clackamas County Jail while prosecutors review the investigation.
Detectives Looking For Anyone Else Who May Have Been Harmed
Detectives have asked anyone who believes they may have been victimized to contact the sheriff’s tip line at 503-723-4949 or use the online tip form, according to the Clackamas County Sheriff’s Office. The tip page notes that messages are reviewed during business hours and offers an option to submit information anonymously. Investigators say tips can help them spot patterns and identify other potential victims.
Charges, Not Convictions
The allegations against Koser are criminal charges and remain unproven unless and until a court decides otherwise. Prosecutors will determine whether to file formal charges after reviewing detectives' evidence. If they move forward, those court filings will lay out the next public steps in the case.
