FORT WAYNE — A 74-year-old man from Fort Wayne was arrested on a felony charge earlier today following a year-long investigation into various crimes against children allegations.

An undercover investigation into peer-to-peer file sharing conducted by the Indiana State Police resulted in the execution of a search warrant at the man’s Fort Wayne residence in April 2015 by the Indiana Internet Crimes Against Children Task Force.

Member agencies include the Indiana State Police, Fort Wayne Police Department, Indianapolis Metropolitan Police Department and the FBI.

Investigators arrested John David Yonkman, Sr. without incident and he was booked into the Allen County Jail under a $2,500 bond.

He is being charged by the Allen County Prosecutor’s Office with possession of Child Pornography, a level 6 felony charge.

Investigators credit the collaborative effort of all of the agencies involved, especially that of the Allen County Prosecutor’s Office, in this complex and highly technical criminal investigation.
