BELGRADE, Maine — Arthur Stilphen, a longtime state and county prosecutor who served as commissioner of public safety during Gov. Joseph Brennan’s administration, has died at the age of 66.

Stilphen, who died Saturday at his home in Belgrade, had retired from the practice of law last year. He continued to work at the North Belgrade General Store that he owned and operated with his wife Brenda.

The Portland native and University of Maine law school graduate is survived by his wife and two children. A funeral service will be held Thursday in Portland.
