Prosecutor: Okla. 3rd grade teacher took pictures, video of naked female students

(CBS/KWTV) SHAWNEE, Okla. - A former Oklahoma elementary school teacher allegedly videotaped her students in their changing room and had them decorate her Christmas tree while wearing lingerie, according to prosecutors in Pottawatomie County.

Kimberly Crain pleaded not guilty Thursday to 23 counts of manufacturing child pornography, conspiracy to manufacture child pornography, and lewd molestation. She is being held on $1 million bond.

Crain was a third grade teacher at McLoud Elementary until last month, when she resigned after female students said she had invited them to her home to decorate for Christmas, then asked them to change into bras and panties and took pictures and video of them.

So far, Pottawatomie County District Attorney Richard Smothermon said 14 victims have been identified, but they suspect there are many more who have not come forward.

According to CBS affiliate KWTV, police later discovered more than 100 photos of naked and half-dressed young girls on Crain's home and work computers. They said she had hidden cameras throughout her classroom, including a video camera in an area covered by a curtain, where the children were told to go undress.

Prosecutors say Crain shared the child pornography with a man named Gary Doby, who the children knew as "Uncle G," a man Crain had her students Skype with during class. Investigators say Crain and Doby met in the mid 1980s when she was a student at Oklahoma Baptist University, and he was an associate professor.

Doby was arrested Thursday in Pennsylvania.
