Joseph Espinoza (defendant) was charged with transporting child pornography. The prosecution called Clifford Holdren as a witness. Holdren testified, over Espinoza’s objection, that he would receive child pornography by calling a phone number and asking for “Joe.” A man identifying himself as Joe would answer, and Holdren would order the pornography from Joe. Holdren stated that he had never met Joe and did not know what Joe looked like. The prosecution also presented evidence that Espinoza’s fingerprint was found on an invoice to Holdren for child pornography. Espinoza was convicted. Espinoza appealed, arguing that Holdren should not have been permitted to testify about the telephone conversations.
