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.

In the days after his murder, a helicopter flew overhead and police dogs ran through the trees. Police looked in storm drains and trash bins nearby for a murder weapon and stopped motorists on Thomas Road seeking tips. Five days after the murder, divers searched an irrigation pond near the 13th hole of the Trumbull Golf Course.
