36-year-old Barry Barney of Gainesville died as a result of his injuries while being airlifted to a local hospital.
2 other men and women were also wounded, one seriously. 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."
Ocasio was arrested during a traffic stop Monday in Marion County. He is charged with one count of attempted murder and aggravated assault with a deadly weapon, but was not charged with murder. Additional charges are pending.
Investigators are not ruling out the possibility of a second shooter.
The shooting happened at about 8pm Saturday evening, as a huge crowd of around 10,000 people gathered at the annual festival on CR 318 in Levy County, east of Williston.
