A Wisconsin auto race shooting left three men dead on Sunday. No suspect was arrested.
Kenosha County Sheriff David Beth said authorities responded to the Great Lakes Dragway in Union Grove around 7 p.m. Sunday after receiving reports about shots being fired, The Associated Press reported.
Beth said the three men were shot by another man at point-blank range near a food vendor. No suspects have been arrested.
Two men died at the scene, and the third died while being transported to a hospital. The sheriff said at least two of the men were from Aurora, Illinois.
The victims may have been targeted by a rival gang member but a lack of cooperation has stymied the investigation, sheriff's officials said Monday.
"Some of the family members, some of the people involved, are not very cooperative with law enforcement. And, that's making it more difficult to investigate this whole thing," Beth said on WTMJ-AM.
Sheriff's Sgt. Mark Malecki said the victims were from the Aurora area in Illinois.
"The victims were known gang members," Malecki said, adding that deputies were investigating the possibility that the assailant was a rival gang member.
Beth urged any witnesses to the shooting to contact his department.
"A lot of people may not have wanted to come up and talk to the sheriff's department initially because maybe they were afraid someone was going to see them," Beth said. "So what I'm hoping happens is someone who knows what's going on or saw what happened will call us, give us more information and help us catch the individual who did this."
The sheriff's office estimated that more than 5,000 people were at the raceway for an event known as "Larry's Fun Fest."
Union Grove is about 25 miles south of Milwaukee.
