A deputy sheriff for Tillamook County was arrested and arraigned Thursday in Tillamook County Circuit Court following a near one month investigation into allegations that he sexually abused a known female over a decade ago.
In August 2010, Tillamook County Sheriff Todd Anderson contacted Oregon State Police (OSP) requesting a criminal investigation related to an allegation that one of his employees, DAVID PROCK, age 56, sexually abused a known female under the age of 17 during the late 1990s.
An OSP Criminal Investigations Division detective was assigned to investigate, working closely with Sheriff Anderson and the Tillamook County District Attorney's Office. Upon completion of the investigation, the Tillamook County District Attorney requested the case be reviewed by the Clatsop County District Attorney's Office. Subsequent to that request, a special prosecutor was assigned from the Clatsop County District Attorney's Office.
On September 23, 2010, a Tillamook County Grand Jury indicted PROCK on one count of Rape in the First Degree and one count of Incest. Tillamook County Sheriff's Office, with the assistance of OSP, arrested PROCK at his Beaver-area home and took him before a Tillamook County Circuit Court judge for arraignment.
Following arraignment, PROCK was being transferred to the Washington County Jail.
According to the Tillamook County Sheriff's Office, PROCK was employed as a patrol deputy for 21 years. He was placed on paid administrative leave September 9, 2010 pending the results of the criminal investigation. Effective today, he was placed on unpaid leave.
