By - Associated Press - Monday, April 5, 2021 ST. LOUIS (AP) - Two white St. Louis police officers will be retried on charges stemming from the 2017 beating of a Black undercover colleague during a protest, federal prosecutors said Monday. Jurors last week acquitted Officer Steven Korte of charges of deprivation of rights under color of law and of lying to the FBI about the attack on Officer Luther Hall. Jurors were unable to reach a decision on some charges against former officers Dustin Boone and Christopher Myers. The attack, which injured Hall so severely that he had to undergo multiple surgeries, happened when Hall was mistaken for a protester during demonstrations that erupted after former white police Officer Jason Stockley was found not guilty in the 2011 death of a Anthony Lamar Smith, who was Black.
