WILLISTON, Fla. -

A 19-year-old man is accused of shooting five people during the annual unsanctioned Crab Festival in Williston.

Authorities arrested Devonte Ocasio on Monday during a traffic stop in nearby Marion County. He was taken to Levy County, where he was charged with attempted murder and aggravated assault with a deadly weapon. Additional charges are pending.

The Gainesville Sun reported 36-year-old Barry Barney of Gainesville died from his injuries while being airlifted to the hospital.

Levy County Sheriff's officials declined to release the names of the other victims. Authorities say fear retaliation because they believe the shooting was "motivated by some type of drug-related crime."

The shooting happened about 8 p.m. Saturday as a crowd of thousands was gathered in Williston.

Officials say they aren't ruling out the possibility of a second shooter.
