KEENE, N.H. (MyKeeneNow) Two tragic deaths in New Hampshire’s Monadnock region—a fatal shooting in Stoddard and the suicide of a police chief in Keene—seemed unrelated at first. But hidden connections, suppressed evidence, and unanswered questions reveal a more troubling narrative.

Michael Carney’s 2017 death, ruled self-defense, has been challenged for years by his sister, Caryn Perkins, who uncovered inconsistencies in the investigation. Her search for answers led to the revelation of a hidden relationship between Michael’s wife, Nicole Carney, and Keene Police Chief Brian Costa, who took his life days after the shooting.

This three-part series by Damien Fisher published on InDepthNH.org this week explores the concealed evidence, flawed investigations, and lingering questions surrounding these intertwined tragedies. Through Perkins’ relentless fight for the truth, “A Matter of Trust” uncovers a case that tests the very foundations of justice and accountability.

Dan Mitchell will interview Fisher about this story on his morning program tomorrow at 9:15 a.m. on WKBK.
