The Smiley Face Murder Theory is one of the most controversial topics within the true crime community with strong support for both sides of the argument. While I personally believe that there was some degree of foul play involved in some of the cases, particularly with the deaths of Patrick McNeill, Tommy Booth, and Dakota James, it is difficult for me to chalk it up to a group of elusive killers operating at such a cohesive level that they fool even the most astute agents of the FBI.
