One of the original "attempts" at a police investigation got blocked and swept into oblivion.

The detective wanted it routed to HOMICIDE ! He must of had some good reasons for that recommendation.
Uh, did you read that report? It says over and over there were no signs of abnormality and the case was pretty much closed as soon as the doctors reported back to the cops. The only reason the word "HOMICIDE" even appears on that report is because they're the ones that always show up when a young, outwardly-healthy-appearing person turns up dead. They're not there because they think a murder took place; it's just SOP.
