The fact that an anonymous letter was sent to authorities is an incredibly troubling detail. This indicates a sort of brazen action, and denotes a dangerous personality -- a person who not only has no problem killing someone, but who has no qualms about pointing out his crimes. The existence of this anonymous letter, and maps, reeks of a "catch me if you can" mentality. In other words, I believe the person responsible for this Jane Doe's death is playing a game of cat-and-mouse with the authorities in Henderson. He (or she) not only derived enjoyment from committing a murder, but they're getting another layer of pleasure out of pointing out his or her crime with the emboldened sense of knowing that they will not be caught -- or will they? In my honest opinion, this behavior has serial killer stamped all over it. And if this isn't a serial killer, he or she very seriously has the potential of becoming one -- especially since they have gone over eight years without being discovered since the death and disposal of this Jane Doe.
On the other hand, the letter could have been sent out of guilt and cowardice. This person may or may not even be responsible for the death of this unidentified woman, but may have first-hand information behind what happened to her. There is a small possibility that this man or woman wanted someone to find the body in hopes of either putting an end to an unresolved situation, or to simply get the guilt of knowing about the death off his or her shoulders.
I'm more inclined to believe the first scenario, over the latter.
Authorities in Henderson have been able to recover just a few more remains associated with this unidentified woman's case. However, her entire body has not been located. Police have also reported that they found some articles of clothing that belonged to the Jane Doe, but photos and descriptions of the clothing have never been produced. They believe that she was a white female between the ages of 25 and 45-years-old. The rest of her features were completely unrecognizable due to there being nothing but partial skeletal remains when she was discovered. This has made it incredibly difficult to identify her. Police in Henderson believe that she had only been dead for a few months by the time she was discovered.
There have been several attempts at identifying this Clark County Jane Doe -- all of which unsuccessful. Among the unsolved cases of missing women in the country, several have already been officially ruled out as being this unidentified woman. Those women include Tina Wilson, April Beth Pitzer, Laurie Steiner, Joey Offutt, Michelle Benjamin, Angela Finger, Jessica Foster, Tammy Lopez and Lindsey Harris. Police have not identified any of the possible matches that have been submitted to them, which have not yet been ruled out.
