A Collier County Sheriff's Office investigation has cleared three deputies of wrongdoing after the NAACP complained that a black man was beaten after a high-speed, 50-mile chase that totaled a trooper's car.

At a press conference Wednesday, Collier County Sheriff Kevin Rambosk said an internal affairs investigation determined three deputies hadn't used excessive force on Coroy Dontavia Flournoy, 26, of Fort Myers, a passenger in a June 15, 2009, pursuit on Interstate 75 that caused a Florida Highway Patrol Trooper to crash.

The sheriff's Professional Responsibility Bureau investigation determined Flournoy was struggling and resisting arrest and the use of force was "lawful and reasonable," within Florida Department of Law Enforcement and sheriff's guidelines.

"The last 20 seconds of video that everyone seems to be focusing on is not the entire story," Rambosk said, referring to the pursuit. "I can tell you that the incident that both Mr. Palmer and Mr. Flournoy were in was dangerous and violent, both to the community and to the deputies involved."
