Prodan succeeded Mary Frank, who decided to retire instead of running for a second term.

[24] Only five municipalities in Franklin County have their own police department (Carrabassett Valley, Farmington, Jay, Rangeley, and Wilton).

Nichols was elected to that post in November 2012, defeating incumbent sheriff, Dennis Pike.

Pike had spent 46 years in Franklin County law enforcement prior to being defeated by Nichols.

In 2008, Governor John Baldacci signed into law a bill which consolidated county jails in an effort to reduce costs.

Public outrage over the jail issue also pressured the state to give the county full service rights.
