After investigating a report that Barger (defendant) had allegedly sexually abused a child, a police officer named Sullivan spoke to Barger’s wife who allowed Sullivan to look at Barger’s computer. The computer was eventually seized by the police who made a copy of its hard drive and examined it. Police detectives found several pictures of naked children in the computer’s Internet temporary file cache. Barger was charged with eight counts of possessing or controlling a visual recording of sexually explicit conduct involving a child in violation of ORS 163.686(1)(a). Each charge was based on a separate digital image that police found in the computer’s temporary file cache. At trial, police detectives acknowledged that there was no way to know with certainty whether the images had been intentionally accessed or were the result of “pop up” advertisements or “browser redirects.” After the close of the prosecution’s case, Barger moved for a judgment of acquittal on the basis that there was no evidence to show that he had intentionally and knowingly downloaded, possessed, or controlled the images at issue. The trial judge denied Barger’s motion and he was found guilty and appealed. The court of appeals affirmed and the Oregon Supreme Court granted certiorari to review.
