I apologize if this is posted elsewhere, but when I searched I was unable to find any mention of this.
On February 9, 1980, Bernice Raymond went to a house used by David Emerich, a 32 year old sex film producer and convicted cocaine dealer. Ms. Raymond's 24 year old sister, Bonnie Pellicer, lived with Emerich. Bonnie, from a prominent St. Augustine, FL family, was a law student.
In the kitchen, Ms. Raymond found blood-stained meat cleavers and knives along with pools of dried blood. A bullet from an automatic pistol was lodged in a cupboard. Near the basement furnace she found a pool of blood and a cutting board containing what was later determined to be human flesh.
Later articles mention a bloody chainsaw.
There a several newspaper articles regarding this case.
Neither are listed in NamUs, Charley Project or Doe Network.
