A former St. Louis County prosecutor who resigned amid a federal investigation in December isn't suspected of any wrongdoing.
An attorney for John Quarenghi told the St. Louis Post-Dispatch that his client had stepped down to spare the office any embarrassment after learning that his electronic communications with paralegal Jillian Nichols were being examined by federal investigators.
Nichols was indicted last week (Feb. 19) on charges of wire fraud and lying to the FBI. She's accused of offering a sexual assault defendant favoritism from an unnamed prosecutor in exchange for $10,000.
Officials say Quarenghi wasn't involved in Nichols scheme, but had dated her.
