Three people are dead after a gunman approached them and opened fire at a racetrack in Wisconsin Sunday.
The trio were among 5,000 people attending Larry's Fun Fest at the Great Lakes Dragaway when they were fatally shot, according to the Kenosha County Sheriff's Department.
CBS reports that two victims died at the scene and the third on the way to hospital.
The sheriff says it's gang related
Kenosha County Sheriff David Beth initially said it wasn't clear what led up to the shooting.
But in a Monday afternoon update, the sheriff's office called it "street gang related."
The victims – all of whom were from the western Chicago suburbs of Aurora and Oswego – were "distinct targets," the sheriff's office said, describing it as "not a random act of violence!"
The suspect is still on the loose
They have not made an arrest in the case.
The sheriff's office described the suspect as a black man, 20-30 years old, with the side of his head shaved. He fled on foot, but authorities think he eventually left the area in a vehicle.
The sheriff's office is searching for a black vehicle thought to belong to the suspect, according to the Milwaukee Journal Sentinel.
According to TMJ4, Beth said witnesses aren't cooperating with law enforcement, and that's making the investigation more difficult.
Anyone with information is asked to call the Sheriff's Department at 262-605-5100.
The event was attended predominantly by people living in southern Wisconsin and northern Illinois at the speedway near Union Grove, and featured a variety of "smaller, souped-up 'Fast and the Furious' type vehicles," the Milwaukee Journal Sentinel notes.
