Seven other suspects in the Haymarket affair…

Seven other suspects in the Haymarket affair are indicted by the grand jury on June 4, 1886, and stand trial for being accessories to the murder of Degan.

Of these, only two had been present when the bomb exploded.

Newspaper editor August Spies and Samuel Fielden both had spoken at the rally and were stepping down from the speaker's wagon in compliance with police orders to disperse just before the bomb went off.

Two others had been present at the beginning of the rally but had left and were at Zepf's Hall, an anarchist rendezvous, at the time of the explosion.

They were: Arbeiter-Zeitung typesetter Adolph Fischer and the well-known activist Albert Parsons, who had spoken for an hour at the Haymarket rally before going to Zepf's.

Parsons, who believed that the evidence against the other defendants was weak, had subsequently voluntarily turned himself in, in solidarity with the accused.

A third man, Spies's assistant editor Michael Schwab (who was the brother-in-law of Schnaubelt) was speaking at another rally at the time of the bombing (he was also later pardoned).

Not directly tied to the demonstration but arrested because notorious for their militant radicalism were George Engel (who was home playing cards on that day), and Louis Lingg, the hot-headed bomb maker denounced by his associate, Seliger.

Another defendant who had not been present that day was Oscar Neebe, an American-born citizen of German descent who was associated with the Arbeiter-Zeitung and had attempted to revive it in the aftermath of the trial.

Of the eight defendants, five—Spies, Fischer, Engel, Lingg and Schwab—are German-born immigrants; a sixth, Neebe, is a U.S.-born citizen of German descent.

Only the remaining two, Parsons and Fielden, born in the U.S. and England, respectively, are of British heritage.
