Police say the Independence Day shooter who killed 7 people contemplated another attack at a parade in Madison, Wisconsin

According to officials on Wednesday, the Highland Park, Illinois, mass shooter, Bobby Eugene Crimo III admitted to investigators that he fired at a crowd during the July 4 parade.

The gunman was charged with seven counts of first-degree murder following a rampage Monday that left at least seven people dead and dozens injured during a court appearance.

Police say he used a legally purchased “high-powered rifle” in the attack and contemplated carrying out a second shooting in Madison, Wisconsin, with an additional weapon he had in his car.

“Investigators did develop some information that it appears when he drove to Madison, he was driving around, however, he did see a celebration that was occurring in Madison, and he seriously contemplated using the firearm he had in his vehicle to commit another shooting in Madison,” said Christopher Covelli of the Lake County Sheriff’s Office.

Crimo also said that he dressed up as a woman and covered his tattoos with makeup to avoid being recognized, according to the prosecutor.

Witnesses have described frantically fleeing when they realized they heard gunshots, not fireworks in Highland Park which is located about 25 miles north of Chicago.

Crimo’s cell phone has since been recovered by the FBI and is now being processed. Investigators have yet to determine a motive. The 21-year-old has been ordered to remain in jail without bond.
