McLOUD — Workers installed windows in classroom doors at McLoud Elementary School during the holiday break, a move made in response to charges that a once-trusted teacher took lewd pictures of students in her classroom. The school district has implemented several changes since the allegations surfaced against former third-grade teacher Kimberley Ann Crain, 48, of Shawnee. The changes include a policy that requires any outgoing Internet attachments to be forwarded to the principal and superintendent, and that classroom doors without windows remain open during school hours, said Lisa Liebl, spokeswoman for the district. Teachers are prohibited from hanging decorations or curtains in the windows to block the view, Liebl said. Crain faces 23 felony counts in Pottawatomie County District Court stemming from allegations that she manufactured child pornography using her students as models to send to former college professor Gary Joseph Doby, 65, of Bloomsburg, Pa. McLoud Police Chief Gary Roe said some of Crain’s female students told investigators Crain would encourage them to expose body parts for her photographs behind a makeshift tent made from garbage bags she erected in the back of her classroom. Crain also allegedly had them video chat on the Internet in the classroom with a man they called “Uncle G.” The man was later identified as Doby, Roe said. Doby has been jailed since his Dec. 14 arrest with bail set at $1 million. An extradition hearing is scheduled for Jan. 9 for a judge to determine whether Doby should be moved to Oklahoma, where he is charged with nine felonies, including manufacturing child pornography and conspiracy to manufacture child pornography. The investigation began when a student’s parent reported to police that his daughter had been at a pizza party at Crain’s home in November where the girl and other students were asked to dress in Christmas-themed underwear and pose for photographs. Crain resigned from her job after the allegations surfaced. Crain was McLoud Elementary School’s Teacher of the Year in the 2006-07 school year, and she passed all criminal background checks when she was hired, Liebl said. Liebl said none of the parents of students making claims against Crain have asked for transfers from the school district. Crain is in the Lincoln County Jail with bail set at $1 million. She was moved from the Pottawatomie County jail because a jailer working there is related to one of the alleged victims, authorities said.
