A Massachusetts man who once worked for Public Storage will spend at least two years in prison for committing five armed robberies at Public Storage facilities.

Zachary Paul, 32, of Milton, MA, admitted robbing three Public Storage facilities in Randolph and Westwood, MA, according to Norfolk County District Attorney Michael Morrissey. The crimes happened in September and October 2013 and in January and February 2014.

David Traub, a spokesman for Morrissey, said Paul had been fired several years ago for stealing from a Public Storage facility where he’d worked. Details about the theft weren’t available.

This May, a grand jury indicted Paul on charges of armed robbery and kidnapping. He pleaded guilty in August.

Drug-fueled crimes

Assistant District Attorney Laura Greenberg-Chao sought a prison term of three to five years, followed by 10 years of supervised probation as well as treatment for a drug addiction that Paul claimed prompted the robberies. Norfolk County Judge Robert Cosgrove sentenced Paul to two to five years in prison, with five years of supervised probation accompanied by drug treatment.

Robbery victims told police that Paul had brandished a black handgun, demanded money, and ordered them into back rooms or bathrooms at the storage facilities, according to Morrissey. Paul told the victims they’d be confined to those rooms until he got away, or else he’d kill them. Under Massachusetts law, the confinement constituted kidnapping.

A former Public Storage co-worker tipped off police that Paul might be the culprit. In March, authorities searched his home, where they found a replica handgun and several pairs of sneakers that appeared to match footprints left at two of the robbery scenes. Paul then confessed to the robberies in Randolph and Westwood.
