Arkansas State Police stated in a Sunday news release that one person was being held and authorities were looking for other people who might have shot into the crowd on Saturday night. Additional information, including the condition of the injured, was not immediately available.
State troopers were sent to Dumas in the 90-mile south of Little Rock at 7:25 p.m., after a report of gunfire at a car show.
Troops from the state's criminal investigation section "worked throughout the night interviewing victims, witnesses," according to the force in its statement.
According to the website of Delta Neighborhood Empowerment Youth Organization, the car show is part a community event that's held every spring in order to raise funds for school supplies and scholarships.
Wallace McGehee (the organizer of the car show) expressed condolences for the families and community.
McGehee stated that it was a tragedy for something like this to occur. "We did it here for 16 years with no problems."
Chris Jones, a Democrat running to Arkansas governor, tweeted he had attended the event earlier in Saturday, registering voters, and enjoying "a positive familial atmosphere".
Jones released a statement saying that he was deeply saddened and angered by the tragedy.
