A trial has been set for a Lewis Center man facing 82 charges involving child pornography.

Dr. David Thomas Ryan, 56, of 3725 Wood Stone Drive, Lewis Center, appeared in Delaware County Common Please Court Friday and entered a not guilty plea to 38 counts of pandering sexually oriented matter involving a minor, second-degree felonies and 44 counts of pandering obscenity involving a minor, second-degree felonies.

Delaware County Common Pleas Judge Everett Krueger accepted the plea and scheduled Ryan to stand trial on May 2. Krueger also set Ryan’s bond at $75,000.

According court documents, Ryan posted bail on Feb. 3 and was released from the Delaware County Jail.

According to the indictment, the pandering obscenity involving a minor charges state that that Ryan “with knowledge of the character of the material or performance involved, did create, reproduce or publish any obscene material that has a minor as one of its participants or portrayed observers…”

According to the indictment, the pandering sexually oriented matter involving a minor state that Ryan “with knowledge of the character of the material or performance involve did create, record, photograph, film, develop, reproduce, or publish any material that shows a minor participating or engaging in sexual activity, masturbation, or bestiality…”

Each count stipulates a different file that Ryan possessed that qualifies as either sexually oriented matter or obscenity.

The Delaware County prosecutor’s office reports the indictment came after it was reported an individual had e-mail transactions known to contain child pornography. The Delaware County Sheriff’s Office, along with the Franklin County Internet Crimes Against Children Task Force, investigated the downloading and file sharing of child pornography.

“It took several agencies working together to ultimately track down Dr. David Ryan,” said Delaware County Prosecutor Carol O’Brien said in a release after Ryan’s indictment. “The result was a search warrant being issued on Dr. Ryan’s home, in Orange Township, and ultimately, his arrest.”

Several electronic items were seized in a search warrant executed at Dr. Ryan’s home. Another search warrant was obtained for an additional electronic item, which was seized at his business, Columbus Chiropractic Center.

According to the Ohio Revised Code, penalties for the charges include between two to eight years in prison and fines of not more than $15,000.
