A GREENE COUNTY GRAND JURY HAS DISMISSED SECOND-DEGREE MURDER CHARGES AGAINST A MAN INVOLVED IN A 2023 SHOOTING DEATH. 27-YEAR-OLD LIAM MACDONALD-GAGNON WAS CLEARED IN THE OCTOBER 2023 SHOOTING OF 42-YEAR-OLD JOHN MCCANN. MACDONALD-GAGNON’S LAWYER STATED HIS CLIENT ACTED IN SELF-DEFENSE AGAINST A THREATENING ASSAILANT. THE ASSISTANT DISTRICT ATTORNEY GENERAL CITED NEW EVIDENCE THAT WOULD HAVE MADE PROSECUTION DIFFICULT. THE INCIDENT INVOLVED A CONFRONTATION BETWEEN MACDONALD-GAGNON, HIS GIRLFRIEND, AND HER EX-BOYFRIEND MCCANN.
