ST. LOUIS • A veteran St. Louis police officer was suspended and two prosecutors left their jobs this week amid internal and criminal investigations into allegations of misconduct.

Police and prosecutors would not reveal the reason behind those developments, citing the ongoing inquiries.

Sources say the officer at the center of the investigation is Detective Thomas A. Carroll, a 25-year veteran of the department.

A police spokesperson confirmed in a statement Friday that allegations of officer misconduct reached the department July 25 via the circuit attorney’s office. The police statement continued:

“The department immediately launched both an internal and criminal investigation. One officer has been suspended without pay. The Department holds its employees to a high standard, therefore, we take these allegations seriously. We are committed to upholding the public’s trust in their police department. The investigation is ongoing, and the department is unable to make any further comments.”

The Post-Dispatch learned that two assistant circuit attorneys, Bliss Worrell and Katherine Dierdorf, left their jobs in connection with the situation.
