Oklahoma City Councilman John A. Pettis Jr. has been living for years off donations sent to charities under his control, prosecutors alleged Friday in an embezzlement and tax fraud case.

Pettis, 35, is suspected of converting at least $165,000 from three charities to his personal use, records show.

A yearlong investigation found he has never filed a state tax return, the records also show.

Pettis is expected to resign by the end of the month from the Ward 7 seat he has held since 2013. He is facing three counts of embezzlement and one count of intentionally failing to file state income tax returns.
