Twelve jurors and six alternates were chosen last week.
The Highland Park parade shooter has changed his plea to guilty on the first day of the trial.
Robert Crimo III is pleading guilty to all 21 counts of first-degree murder and 48 counts of attempted murder. He was accused of killing seven people and wounding dozens more at Highland Park’s Fourth of July parade in 2022.
The suspect rejected a plea deal last summer.
Crimo will likely spend life in prison without the possibility of parole.
