NEWARK, N.J. (CBSNewYork) — The FBI may be closer to cracking a pair of jewelry store robberies in New Jersey.

A couple of unsolved jewelry store robberies in Wall Township and Old Bridge, dating back to 2007 and 2009, may have been committed by the same people, officials announced Thursday.

Police linked the cases after studying details from the incidents and surveillance video.

The alleged robber was armed with a handgun and wore a clear, plastic mask and had his keys on a lanyard around his neck. Police said in one of the videos, an accomplice, who was not wearing a mask, could be seen.

The cases may also be linked to two auto thefts on Staten Island. Police said two box trucks used as getaway vehicles in each incident had both been stolen from within a block of each other on Staten Island.

Authorities believe the duo has ties to the borough.

Witnesses in each incident said the robbery suspect carried a two-way radio, possibly to communicate with the driver of a car seen at both hold-up sites.

Police describe the suspect as a white male, about 5’10”, stocky, and 180-200 pounds.  He was also right-handed. The suspect  had his head covered in both robberies, possibly to hide a bald or shaved head, or distinguishing mark.

Anyone with information is asked to call the Wall Township Police Department at (732) 449-4500, the Old Bridge Police Department at (732) 280-4222 ext. 157, or the FBI at (973) 792-3000.
