Felix Arroyo opened up a vacancy as Suffolk County Register of Probate when he retired earlier this month. The first person to officially signal he's running for the office, by registering a campaign with the state Office of Campaign and Political Finance, is Vincent Procopio of Saugus.
Saugus is not in Suffolk County, but unlike candidates for district attorney or register of deeds, registers of probate don't have to live in the county they want to serve. The job entails overseeing a state-funded office for handling wills and the like. It pays $174,000 a year.
