OKLAHOMA CITY - Pottawatomie County prosecutors say a former McLoud Elementary School teacher and a  Pennsylvania professor accused of taking pornographic pictures of children met years ago at Oklahoma Baptist University.

Prosecutors charged Thursday Kimberly Crain and Gary Doby with nearly two dozen counts of manufacturing child pornography and conspiracy to manufacture child pornography.  Crain, a former third-grade teacher, and Doby, a former childhood development professor at Bloomsberg University of Pennsylvania, apparently met in the mid 1980s when she was a student at OBU and he was an associate professor.

Pennsylvania State Police arrested Doby Thursday at his home, a few days after FBI agents executed a search warrant. Doby was previously known only as "Uncle G," a man Crain had her students Skype with during class.  Crain is accused of taking pictures and video of half-dressed and naked young girls, and sharing them Doby.

Doby is being held on $1 million bond.  Prosecutors are working on extraditing him to Oklahoma but they don't know when he will be brought to the state.

Investigators have identified 14 alleged victims of Doby and Crain, but Pottawatomie County District Attorney Richard Smotherman says there are likely more who have not come forward.
