On a quiet cul-de-sac, a husband and wife of 47 years are stabbed to death in the stillness of dawn. Honest and unassuming, John Sheridan, famous for never raising his voice, played against type in the rough-and-tumble world of New Jersey politics. Could the Republican lobbyist have killed his wife Joyce—a veteran public school teacher and no-nonsense mother of four sons—then set their bedroom on fire before knifing himself? That’s the version of events authorities say happened in the early morning hours of September 28, 2014. But, in more ways than one, the theory doesn’t add up.
