A few dates of the actual event:
Oct. 6, 1880. Patrolman James Brady shot and killed at the Charles Starkes saloon, in a "hail of bullets" as police tried to make arrests following a brawl.
Harry Duncan arrested and convicted.
A series of appeals kept Duncan alive until July 7, 1894, when he was hanged.
The case was finally decided by the Supreme Court when the appeal was denied. African-American attorney Walter Moran Farmer presented Duncan's case, and was the first of his race to appear before the court.
Duncan alleged that the bar owner, Charles Starkes, shot Brady.
