The FBI is offering a sizable reward to find the man who shot dead three people in broad daylight at a drag race event in Wisconsin.
The triple shooting, thought to be gang-related, shocked onlookers attending Larry's Fun Fest at the Great Lakes Dragaway in Kenosha County on Aug. 13.
The assailant approached the three men from Illinois and shot them at point blank range.
The FBI on Tuesday released an appeal for information leading to the identification and arrest of the person/people responsible for the killings, and is offering a reward of up to $25,000.
The three victims were among the 5,000 people attending the event.
At the time, the Kenosha County sheriff described the suspect as a black man aged 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 black vehicle.
Investigators also found it difficult to get information from witnesses, who were said not to be cooperating with law enforcement.
