Mass. Gen. Laws ch. 274 § 3
Whoever counsels, hires or otherwise procures a felony to be committed may be indicted and convicted as an accessory before the fact, either with the principal felon or after his conviction; or may be indicted and convicted of the substantive felony, whether the principal felon has or has not been convicted, or is or is not amenable to justice; and in the last mentioned case may be punished in the same manner as if convicted of being an accessory before the fact. An accessory to a felony before the fact may be indicted, tried and punished in the same county where the principal felon might be indicted and tried, although the counselling, hiring or procuring the commission of such felony was committed within or without the commonwealth or on the high seas.
