So there are still thoughts that Kelsey "walked" away from her life. Leaving with no possessions other than a phone and purse. No cars missing. Buns on the counter. No alarms raised with her mother on the last phone calls. No effort to leave things in order in her absence. No reports from authorities backing up her walking away;. withdrawals, texts etc. The investigators would probably not create a situation where fingers are pointing at innocents when they suspect otherwise. Nationwide awareness of her plight and no sightings- she would have to be intentionally avoiding detention. Possible options for leaving on her accord:
1) Kelsey left and went away with someone that no one knows about, and she is fine. She could potentially stay out of view for a month, as her "unknown" companion could leave the paper trail. Her prior contact with this person would have to have no electronic signature. My guess at number of past cases remotely close to this situation= zero.
2) Kelsey left with a plan to stay of the grid despite reports that she is not a hiker or outdoorsy. Hard to find a place to stay although with someone cooperating, although it is possible. Need a significant amount of cash, solid preparations, and some effort at disguise for cash transactions. My guess at number of past cases remotely close to this situation involving a female= zero.
3) She leaves with someone she met, and the investigators have missed the clues. A month later and no evidence has been uncovered to support this scenario. My guess at number of highly publicized cases with gross negligence by the FBI; and involving a female= zero.
4) Kelsey walks away and commits suicide. This happens obviously more than we would like. Usually there are a least subtle warning signs, none obvious with Kelsey. She seemed a bit isolated in Woodland Park without a lot of acquaintances, so we really don't know her state of mind. If she did this, she would have had to intentionally do it in a way that her body would not easily be found. This would be unusual for a female suicide, basically causing increased and prolonged pain for her family. My guess at number of past cases remotely close to this situation involving a female= maybe zero or one?
Certainly there are more options and they would get more extreme and bizarre. Low probability with what ever is proposed.
Considering all the circumstances around her disappearance, it seems to me that there is no chance Kelsey left on her own accord. I hope for options 1 -3 and anything similar, but to me there only seems to be foul play involved, with the intent for her to never be found. I cannot come up with any other explanation when considering the details surrounding her disappearance.
