The man accused of killing seven people and wounding dozens of others appeared in court for the first time since the massacre at a Fourth of July parade in Highland Park, Illinois.
Prosecutors said that Robert E. Crimo III admitted to investigators that he opened fire on the crowd of revelers. They also revealed that the 21-year-old drove to Madison, Wisconsin, where he considered committing another shooting.
"We don't have information to suggest he planned on driving to Madison initially to commit another attack. (But) we do believe that he was driving around following the first attack and saw the celebration," Lake County Major Crime Task Force spokesperson Chris Covelli said.
Officials said they are still working to determine a motive for the attack.
"He went into details about what he had done. He admitted to what he had done," Lake County State's Attorney Eric Rinehart told reporters. "We don't want to speculate on motives right now."
Crimo is being charged with seven counts of first-degree murder and faces a mandatory sentence of life in prison without the possibility of parole. Officials said they expect to file additional charges as the investigation continues.
A judge ordered that Crimo be held without bond and scheduled a preliminary court hearing for July 28.
