Lewis says Knowlton was chosen from about 35 people in the class for a "shoot/don't shoot" simulation. He says she was taken to a hospital, where she was pronounced dead.
The officer involved has not been identified and is on administrative leave pending a Florida Department of Law Enforcement investigation, Lewis says.
