NEWPORT, R.I. – Police have recovered the last of several antiques stolen April 28 and 29 from The Breakers, a seaside mansion in Newport that was once railroad magnate Cornelius Vanderbilt’s summer “cottage.”

A bronze obelisk made by Tiffany was discovered in the family car of one of four Salve Regina University students accused of stealing the items.

The mother of Avery Lloyd, 19, of Portland, Maine, turned the item over to police late Wednesday.

William Elliott, 18, of Peabody, Mass., and Lloyd were charged Thursday with felony breaking and entering. Eric Fudge, of Boxford, Mass., and Joseph Sullivan of Scarborough, Maine, both 18, were charged Wednesday with similar offenses. All have been released on $500 bail.

After the break-ins, mansion officials reported missing the obelisk, a Louis XVI-style mantel clock, a glass vase, three silver vases, a candelabrum and a bronze cast figure by Gertrude Vanderbilt Whitney. Later, mansion officials discovered two of the silver vases had been moved before the break-in and were not taken.

A silver inkwell, two books and a bust of Hermes, the Greek god of trade and profit, were also stolen, but have been recovered.

University officials have begun disciplinary proceedings against all four students, university spokeswoman Kristine Hendrickson said Thursday. She said she could not reveal details.

The Breakers was undergoing repair work that may have undermined its security system. The mansion, modeled after the 16th century Italian palaces of Genoa and Turin, is one of the most-visited attractions in Rhode Island and hosts 300,000 visitors annually.

Police have said they got a break when the university’s security director overheard a snippet of conversation that he reported to detectives. Police did not elaborate on the conversation.

The Breakers was built along a mile-long stretch of Newport coastline dotted with opulent mansions. It is not far from Rosecliff, the house that served as the setting for the 1974 film version of “The Great Gatsby,” starring Robert Redford.
