Tallahassee's police chief is among 56 people vying for the top post at the Florida Department of Law Enforcement.
Chief Walt McNeil made the announcement to his command staff.
The chief is out of town, but his co-workers at the department say they support his decision.
The commissioner position opened up in April with the resignation of Guy Tunnell. He quit in the wake of the controversy surrounding the boot camp beating of Martin Lee Anderson.
Deputy Chief Rafael Hernandez of the Tallahassee Police Department said, "He's always encouraged all of us to make sure we keep on expanding our horizons, anything that would help the community, anything we can do to enhance our skills and better ourselves, and because of that wholesome environment we have, everybody is supportive of what the chief wants to do."
The governor's office will narrow the list in September. At that point the governor will make the appointment.
