Incident

Patrolman Timothy O'Sullivan died of gunshot wounds received at the Haymarket Riot. Patrolman O'Sullivan served with the Chicago Police Department for less than five years and was assigned to the 3rd Precinct. He was survived by his four children. Eight men were arrested and charged with the officers murders. Seven were convicted of murder and sentenced to death. The other one was sentenced to 15 years. On November 11, 1887, four of them were executed by hanging. The day before one of the suspects killed himself in his cell with a smuggled dynamite cap which he detonated in his mouth. The other three were pardoned by Governor Altgeld in 1893. Eight police officers were killed during the Haymarket Riot labor dispute. The officers were at the scene of a civil disorder when the rioters opened fire and threw a bomb into the crowd. Eight police officers suffered fatal wounds and 70 other people were injured by the gunfire and explosion. The officers who were killed included Patrolman Mathias Degan, Patrolman John Barrett, Patrolman George Miller, Patrolman Timothy Flavin, Patrolman Thomas Redden, Patrolman Nels Hansen and Patrolman Michael Sheehan. Patrolman Timothy Sullivan succumbed to his wounds two years later, on June 13, 1888.
