ARCADIA, Fla. — A teenager was fatally shot at a county fair in rural Florida known for its annual rodeos, authorities said Sunday.

The Arcadia Police Department said in a statement that the shooting of the 17-year-old boy at the DeSoto County Fairgrounds on Saturday appeared to be an isolated incident and there were no further threats to the public. The gunman had not been captured by noon Sunday.

No further details have been provided.

Due to the fatal shooting, the DeSoto County Fair Association shut down half Sunday, saying the only events taking place would be a cattle grooming contest and a DeSoto County Jr. Miss pageant. The pageant would be limited to contestants, exhibitors and family members, the association said in a statement.

Arcadia is located almost 90 miles southeast of Tampa. It is home to the oldest rodeo event in the state, the Arcadia All-Florida Championship Rodeo.
