HOLDENVILLE, Oklahoma - An OSBI child pornography investigation lead to four arrests in Holdenville Thursday.

One man arrested is the Director of Transportation for Holdenville Schools.

OSBI said an undercover agent opened an investigation into Terry Farris, 50, in October. The agency said Farris shared images containing child pornography with the agent online.

Agents served a search warrant Thursday and seized computer-related evidence in Farris's home and Farris was arrested at the Holdenville bus barn, where he works as the Director of Transportation for the school district.

He's being held on complaints of possession of child pornography, distribution of child pornography, and violation of the Oklahoma Computer Crimes Act.

In the same town and on the same day, agents arrested Billy Ray Blaylock, 26, at 511 South Hinckley, where he lived with his mother.

He was arrested on complaints of possession of child pornography, distribution of child pornography, possession of marijuana within 1,000 feet of a school, and violation of the Oklahoma Computer Crimes Act.

While they were at it, agents also arrested Blaylock's mother and aunt. The mother, Mary Ann Chronister, 55, and the aunt, Lillian Fay Chronister, 51, were also booked into the Hughes County jail on drug and weapons complaints.

OSBI said that investigation originated with the Edmond Police Department, who turned it over for jurisdictional reasons.
