The Highland Park, Illinois, shooting suspect disguised himself in women's clothing before he fired off more than 70 rounds from a high-powered rifle into crowds gathered for a Fourth of July parade, authorities said Tuesday.
The 21-year-old suspect opened fire on top of a roof of a business in the Chicago suburb on Monday, killing six people and wounding more than 30 others.
During the attack, the suspect donned women's clothing, Lake County Major Crime Task Force spokesman Christopher Covelli said during a press briefing on Tuesday.
"Investigators do believe he did this to conceal his facial tattoos and his identity and help him during the escape with the other people who were fleeing the chaos," Covelli said.
