Occasionally, a celebrity death will NOT be followed by other worthy deaths in succession. These so-called orphan deaths are notable for their rarity.
In the week since Walter Cronkite died, there have been deaths running the gamut from unknown boxers and would-be pro wrestlers to faded Olympic medal winners to authors (including the unfortunate soul who penned the book that became the film "Angela's Ashes") to Taco Bell dogs to Brazilian actresses and German filmmakers.
However, none of these deaths were notable enough to merit further consideration. Therefore, the Death Trilogy Commissioner rules that there will be no death trilogy associated with Walter Cronkite.
