For the state statute on the issue, see: https://malegislature.gov/Laws/GeneralLaws/PartIV/TitleI/Chapter266/Section30
I will let you all debate the specifics now that you have them. I would note that he may have been charged under the local municipal code, but that is not freely available.
The relevant part of the statute:
Whoever steals, or with intent to defraud obtains by a false pretence, or whoever unlawfully, and with intent to steal or embezzle, converts, or secretes with intent to convert, the property of another as defined in this section, whether such property is or is not in his possession at the time of such conversion or secreting, shall be guilty of larceny, and shall, if the property stolen is a firearm, as defined in section one hundred and twenty-one of chapter one hundred and forty, or, if the value of the property stolen exceeds two hundred and fifty dollars, be punished by imprisonment in the state prison for not more than five years, or by a fine of not more than twenty-five thousand dollars and imprisonment in jail for not more than two years; or, if the value of the property stolen, other than a firearm as so defined, does not exceed two hundred and fifty dollars, shall be punished by imprisonment in jail for not more than one year or by a fine of not more than three hundred dollars; or, if the property was stolen from the conveyance of a common carrier or of a person carrying on an express business, shall be punished for the first offence by imprisonment for not less than six months nor more than two and one half years, or by a fine of not less than fifty nor more than six hundred dollars, or both, and for a subsequent offence, by imprisonment for not less than eighteen months nor more than two and one half years, or by a fine of not less than one hundred and fifty nor more than six hundred dollars, or both.
