Retired Pa. professor and ex-Okla. teacher enter pleas in child porn case

(CBS/AP) SHAWNEE, Okla. - A retired professor of early childhood development has pleaded guilty to child exploitation and pornography charges in Oklahoma and an ex-third-grade teacher has pleaded no contest in the same case.

Gary Doby, of Bloomsburg, Pa., was sentenced to life in prison Wednesday. Former teacher Kimberly Crain of Shawnee pleaded no contest and faces a minimum of 25 years in prison at her sentencing March 22.

Prosecutors allege that Crain took photos of more than a dozen young girls while they were changing clothes in her classroom and at her home, then shared the images with Doby.

According to CBS affiliate KWTV, the students knew Doby as "Uncle G," and prosecutors say Crain would make the children speak with him via Skype during class.

Crain and Doby met at Oklahoma Baptist University in the 1980s when she was a student and he was an adjunct professor, KWTV says.

The two were arrested in December 2011 after a student told her parents about the lewd photos, KWTV reports. They were both charged with sexual exploitation of a child under 12, conspiracy to commit sexual exploitation and lewd molestation. Crain was also charged with possession of juvenile pornography.
