Nov. 3: After a three-day open inquest, a coroner's jury recommends that homicide charges be filed against Brentwood Lt. Milton Mulholland, Baldwin Borough Patrolman Michael G. Albert, Brentwood Patrolman John Vojtas and Sgt. Keith Henderson and Patrolman Shawn Patterson, both of the Whitehall force.

Dec. 13: Rowley declares a mistrial in the Mulholland-Albert retrial after the jury deadlocks 11-1 for acquittal. The lone holdout for conviction is the only black juror, who later said he was convinced of the officers' guilt and would have held out until "doomsday."
