The defendant, Daniel Horne, was convicted by a Superior Court jury of second-degree murder, possession of ammunition without proper firearm identification (“FID”), and two separate counts of unlicensed carrying of a rifle in an unpermitted area. The defendant appealed, arguing for reversal of his convictions due to the numerous errors that occurred at trial. The Supreme Judicial Court of Massachusetts (“SJC”) vacated and set aside the conviction of second-degree murder, but affirmed the other convictions.
