William Spicer Jr. was stabbed to death on March 15, 1995, on his Christmas tree farm in Groton. He was found dead inside his tan Ford Taurus on a dirt road at the 27-acre Sparkle Lake Christmas Tree Farm. He had been stabbed multiple times in the neck and abdomen. Beginning today, "Case Unsolved" takes on the Spicer murder case. The state has long offered a $50,000 reward for information leading to an arrest and conviction. Spicer's face is featured on wanted posters and he is the "king of hearts" in a deck of playing cards distributed to inmates. In 2011, divers searched Sparkle Lake in Groton looking for clues, and the investigation remains active.
