A Dukes county grand jury returned indictments last week against a former state probation officer who faces cocaine trafficking charges and two Oak Bluffs men who have been charged in connection with robbing an elderly Island man of his life savings.

Two Vineyard Haven men were arrested in Oak Bluffs on Friday afternoon after they were found with a quantity of drugs, including heroin, marijuana, hashish and prescription drugs, police said.

Oak Bluffs police arrested Jeffrey Sylvia, 23, and Jeffrey Rancourt, also 23, both of Vineyard Haven, at about 2 p.m. Friday in the Our Market parking lot, where they were in Mr. Rancourt’s pickup truck. “The two men had arrived to make a drug deal,” a press release from the Oak Bluffs police said.

The spring sitting of Dukes County superior court wrapped up this week, with a jury convicting a Jamaica Plain man of drug trafficking. Several trials scheduled for the October superior court session.
