ATTLEBORO - State police and FBI agents searched a safe deposit box at a Saugus bank Tuesday and recovered 27 Super Bowl rings they say are linked to the E.A. Dion Co. heist and are valued at at least $250,000.

Troopers and FBI agents executed a search warrant and opened the safe deposit box with one of two keys recovered from the home of Lynn moving company owner Sean D. Murphy, the alleged mastermind behind the June 6 break-in at the Dion factory in the Attleboro Industrial Park, Attleboro Detective Richard Campion said.

"It's obviously a key piece of evidence linking Sean Murphy to more items stolen from E.A. Dion. They're very unique items we wanted to recover," said Campion, one of the local lead investigators into the largest jewelry heist in the city's history.

New York Giants Super Bowl rings manufactured by E.A. Dion were among an estimated $2 million in gold rings, gems and jewelry stolen from the plant by daring thieves who disabled the company's alarm system and gained entry by cutting a large hole in the roof.

City police have been working with the FBI and state police since the break-in, which remains under investigation. Murphy, the owner of North Shore Moving Co., was arrested Friday and was being held at the Essex County Jail on $250,000 bail on charges of receiving stolen property. He is expected to be arraigned in Attleboro District Court Thursday on charges of larceny, breaking and entering and possession of burglar's tools, authorities said.

The safe deposit box state police and the FBI opened Tuesday was under the name of Kristen A. Sullivan, 22, who was identified as Murphy's girlfriend, Campion said.

She gave police a Saugus address when she was arrested Friday at Murphy's home and charged with receiving stolen property along with Murphy. However, police believe she has been living with Murphy, Campion said.

During a search of Murphy's home, police found two safe deposit box keys, one of which was linked to Murphy. Police used it to open a safe deposit box at a bank in Lynn, where police recovered rare coins allegedly stolen from E.A. Dion, Campion said.

State police and the FBI did not know who owned the other key until they continued to investigate and discovered it opened a box under Sullivan's name, Campion said.

After her arrest on Friday, Sullivan was released on bail. She was arrested again Tuesday on new charges of receiving stolen property related to the recovery of the rings, and was in custody Tuesday night at the Saugus Police Department, the detective said.

The rings recovered Tuesday were in addition to at least $100,000 worth of gold rings, including a mock SuperBowl ring, and numerous documents allegedly linking Murphy to the Dion heist, police said.

Also recovered last Friday was a receipt allegedly indicating Murphy sold gold to a company in Pennsylvania and received $50,000, police said.

In addition to the jewelry heist, police say Murphy is a suspect in the 2006 break-in of the AmerisourceBergen pharmaceutical warehouse in Mansfield.

Thieves stole more than a million prescription pills in that heist with a street value of tens of millions of dollars.
