Officials recovered a "high-powered rifle" from the scene where a gunman opened fire — killing six people and sending another 24 to the hospital — at a Fourth of July parade in Highland Park, Illinois, on Monday, authorities said at a press conference.
According to Chris O'Neill, the Highland Park Police commander, "firearm evidence was located on a rooftop of a nearby business," where multiple witnesses told local news broadcaster WGN they saw the gunman start shooting three-quarters of the way through the parade at about 10:14 a.m. local time.
The suspect — described by police as a white man between 18 and 20 years old, with long dark hair, a small build, and wearing a t-shirt — remains at large.
Christopher Covelli, a spokesperson for the Lake County Major Town Task Force, said that the shooting "appears to be completely random" and added that it seemed "like spectators were targeted."
He didn't disclose a motive for the shooting, telling reporters that officials "don't know what his intentions are at this point" but "would still consider him to be armed and dangerous."
The Highland Park Mayor and city council's office instructed parade attendees to shelter in place as more than 100 law enforcement officers search for the suspect.
The FBI is helping to investigate and search for the suspect. The bureau requested that anybody with video of the area contact them to share the footage by contacting investigators at 1-800-CALL-FBI.
