ST. LOUIS (AP) — The special prosecutor overseeing the investigation of how St. Louis Circuit Attorney Kim Gardner prosecuted the criminal case against former Missouri Gov. Eric Greitens has confirmed the investigation is still ongoing.

Special Prosecutor Gerard Carmody on Thursday took the unusual step of putting out a statement clarifying that while a grand jury disbanded Monday, the investigation continues.

The statement offered no further details and a spokesman for Carmody declined comment.

The statement was released hours after Gardner spoke at a news conference calling for an end to the investigation.

She was surrounded by about three dozen black leaders.

Gardner is the city’s first black female circuit attorney.

The grand jury last month indicted William Tisaby, an investigator hired by Gardner, accusing him of lying during a deposition in the criminal case that was a factor in Greitens’ decision to resign last year.

Gardner’s office charged Greitens with invasion of privacy for allegedly taking an unauthorized, compromising photo of a woman during a 2015 affair.

The charge was later dropped.
