ST. LOUIS, MO (KTVI) – A former city police detective will spend 52 months months in federal prison for a civil rights violation. Former city police detective Thomas A. Carroll, 52, admitted beating a handcuffed suspect, but denied ramming a gun into the man’s mouth,.

The judge’s decision centered around Carroll’s rage at Michael Waller, who was caught with the officer’s daughter’s stolen credit card and an effort by assistant circuit attorney Bliss Barber Worrell to cover up the attack.

Carroll and Worrell both resigned from their jobs, and pleaded guilty to crimes.
