Opening statements were scheduled to start Tuesday in the trial of four men charged in the deadly 2003 stampede at E2 nightclub in Chicago.

Twenty-one people were killed in the incident and more than 50 were injured.

Club owner Dwain Kyles, his partner Calvin Hollins Junior, club manager Calvin Hollins III and party promoter Marco Flores are charged with involuntary manslaughter.

Prosecutors say the four violated a Housing Court order to close the club.

A jury will hear the case against Kyles at the same time a judge decides the fate of the other three.
