Serial killer Edward Wayne Edwards confessed that he planted Laci Peterson’s remains where they were discovered.
Margot: “He told me about parking the car and walking by the tree, going past the puddle, and taking the walk down to where he could direct how the body was positioned. The raft floated between the two rocks and the body was lifted to the flat rock.”
This adds to the existing evidence that Edward Wayne Edwards was involved : two anonymous confessions, the “Message from God” and the “I Killed Laci Peterson” messages. See Who Killed Laci Peterson.
