Three people were shot dead at a drag race track in Wisconsin on Sunday, authorities said, but it was unclear who was responsible and what the motives might have been.
The shooting took place at the Great Lakes Dragaway in Union Grove, Wisconsin, Kenosha County Sheriff David Beth said.
Several thousand people were at the track at the time, which was evacuated. About 100 police officers responded to the shootings, interviewing witnesses, combing for evidence and helping with the investigation.
No suspects were held in custody, authorities said.
