Jurors hearing the largest street-gang trial in recent Chicago history are being told that members of the Hobos gang lived by a creed that required killing perceived enemies, including an informant who likely would have testified at the trial.

Government attorneys began their closing arguments Thursday at the racketeering conspiracy trial of six alleged Hobos members, including purported leader Gregory Chester.

Prosecutor Timothy Storino told jurors the men treated Chicago's South Side "like it belonged to them." He said that after Chester's arrest, one subordinate killed gang associate-turned-informant Keith Daniel in front of his stepchildren in 2013.

The trial comes during an especially violent year in Chicago. There have been more than 700 homicides since January.

Six defense lawyers will also address jurors. Closings are expected to last four days.
