This infamous murder has been the subject of intense and sometimes
bizarre speculation and theorizing. At least six authors claim to have
solved the murder, each offering a different solution. Two separate and
unrelated people have published sensationalistic books claiming that
their fathers committed the crime. Another author suggested filmmaker
Orson Welles as the killer. Author and screenwriter Donald H. Wolf has
written yet another book on the case, to be published in 2005,
promising to implicate an as-yet-unnamed "Hollywood mogul" in the
crime.
