BANGOR, Maine — A federal judge on Monday ordered that a Sangerville man charged with possession of child pornography be held without bail until at least Wednesday.

John McKenzie, 45, was arrested Friday, according to court documents. He made his first appearance Monday before U.S. Magistrate Judge Margaret Kravchuk in U.S. District Court. She scheduled a bail hearing for McKenzie on Wednesday afternoon.

The U.S. Attorney’s Office, which is prosecuting the case, has asked that McKenzie be held without bail pending the outcome of his case.

McKenzie allegedly exchanged images of child pornography in September 2010 with an FBI agent in Missouri who was posing as a man interested in sharing images.

In December 2010, Maine law enforcement officers seized McKenzie’s computer and found child pornography on it that he had sent to the FBI agent in Missouri, according to court documents.

The Sangerville man allegedly used three images of girls he knew and morphed them with pictures of naked men to make them appear sexual in nature. The girls were 10, 12 and under the age of 18 when the pictures used were taken, according to court documents.

The younger two girls, who still live in Maine, were interviewed and denied any abuse by McKenzie, an FBI affidavit stated.

If convicted, McKenzie faces up to 10 years in prison and a fine of up to $250,000.
