Sheriff is elected, not appointed. Needs recall election.
In Florida the governor can replace any constitutional county officer, including sheriff, tax collector, supervisor of elections, etc.
Florida Statutes, Chapter 112.51 Municipal officers; suspension; removal from office.
(1) By executive order stating the grounds for the suspension and filed with the Secretary of State, the Governor may suspend from office any elected or appointed municipal official for malfeasance, misfeasance, neglect of duty, habitual drunkenness, incompetence, or permanent inability to perform official duties.
IMHO, Scott should suspend him immediately.
