Prosecutors had said that nearly all of the 48 survivors from that day planned to testify.
Prosecutors had also turned over thousands of pages of evidence, as well as hours of a videotaped interrogation, during which police say Crimo confessed to the shooting.
Crimo, 24, had previously pleaded not guilty and rejected a plea deal last year.
