The detective who spoke about Vandy Jane Doe in this episode of The Fall Line podcast said this:
“Every death investigation should be approached as a homicide. The reason for this is sometimes the manner of death is not obvious or the scene could be staged to appear as something else, such as an accident or suicide. In some cases, even a natural death rather than a homicide. If the scene is not properly investigated and it is later determined that the death was a homicide, potential evidence could be lost and that could mean the difference between solving the case or the case going cold.”
