Spectators were 'targeted' in the deadly Highland Park Fourth of July parade shooting, authorities say

• A gunman opened fire on a Fourth of July parade in Highland Park, Illinois, killing 6 people.
• The spectators were "targeted," according to police.

Parade spectators at a Fourth of July event in Highland Park, Illinois were "targeted" by the gunman in the deadly mass shooting, police said.

"It sounds like spectators were targeted," said Christopher Covelli, spokesperson for the Lake County Major Town Task Force.

The mass shooting left 6 people dead and at least 24 injured. The shooter is still at large, police said.

Covelli didn't disclose a motive for the shooting but said it "appears to be completely random."

"We don't know what his intentions are at this point," Covelli told reporters.

The gunman opened fire from a nearby roof when the parade was about three-quarters of the way finished. Investigators later found a "high-powered rifle" on the roof.

"You have a tragic, mass act of violence that was random here, today, at a community event where people were gathered to celebrate," Covelli said.

The FBI is working with local police to catch the shooter.

The bureau requested that anybody with video of the area, including cell phone photos and videos from witnesses and business owners, contact them to share the footage by contacting investigators at 1-800-CALL-FBI.
