Galveston county Daily News, April 16, 2007 GALVESTON - A substitute teacher remained in jail Saturday, but the images that put him there are on their way to Virginia. The National Center for Missing and Exploited Children will review computer discs with photographs at the heart of a child-pornography case on the island. Before the arrest, investigators showed what they called four of the most egregious images to Dr. James Lukefahr. Lukefahr is a University of Texas Medical Branch pediatrician and medical director of the ABC Clinic, which examines children in cases where abuse or neglect is a possibility. He said Saturday there was no mistaking who and what the pictures depicted.
