A few things popped in my mind after reading this thread.
The missing bedsheets:
Like someone said, may have been used to wrap her body...but I'm thinking more along the lines of DNA (or both). Did she perhaps have a family member or any friend who came out to visit her as she was elderly? Someone who may have slept in the same bed, therefore leaving trace evidence behind (hair, clothing fibers,etc.). The missing bedsheets tell me this person planned to leave with all the DNA he came in with; as there were also no signs of forced entry, I'm convinced this person more than likely spent the night there and knew Stephanie very well. The "last link on the left" article posted earlier in the thread has an interesting statement where an Alberta Sustainable Resources spokesman stated "spotters do not have to be out there alone. They can have pets, a spouse, friends, family & pets stay with them."
*I am not saying she was raped or had consentual sex with someone, although that is a possibility in regards to the bedsheets*
The mention of a missing watch:Very strange to mention this...of all things to note missing, a watch but there is no description to be found of it. This must be a very strong piece of evidence to note as missing. Was it that valuable or does it have a certain inscription on it to identify it as hers? I'm thinking this a ploy by investigators to trick the perp into thinking it's valuable, thereby hoping to trick him into pawning it off. If she wore jewlery, you'd think there'd be mention of other pieces like rings or a necklace. There is a key significance to this watch when read between the lines.
Absence of blood or signs of a struggle:No reported evidence of either as most of the time it is reported if there was a struggle or not. All that was left was a pot of water on the stove...one report states it was a pot, another a kettle. Small difference, but significant all the same. One important question which has not been asked yet is were there any coffee cups left out at the scene? Just one...or was there two, meaning she had company and planned on sharing her morning coffee. Call it a force of habit, but when I make coffee at home, I grab my cup out of the cupboard before it's ready. Most of the guys do the same here at work as well and now that I think of it, I recall my parents doing the same. Not saying she did the same thing, but it is possible. She may not have had a chance to get them out though if she was attacked when she turned her back. This makes me think there was some sort of inhalant used to knock her out, like chloroform or something similar to it. She may have been 70, but according to those who knew her, she was tough as nails so you'd think there'd be signs of a struggle...unless she was somehow subdued very quickly.
Tangibles: As her vehicle was left there, the perp had his own method of transportation. How closely was the employee checking in on her interviewed...not saying he/she should be a suspect, but this person had to have missed the perp by about 10 minutes if the water was still boiling. There's only one road in and one road out to Highway 40 from the tower (or so it appears) so I wonder if this person recalls seeing any vehicles on Hwy 40 on his/her way out to the tower. It is known the weather was dry, so there would have been dust and lots of it from the gravel road to the tower (photos show gravel); if this person recalls seeing dust in the air then it did happen minutes prior to his/her arrival. Lastly, when did she last check in...S.R.D. states their spotters check in 3 times per day. I'm assuming morning, noon & evening. All it says is she didn't check in for her morning report, so she had to have checked in the night prior otherwise they would have gone out the night prior. Two things with this: The perp was already there and she knew this person well enough to not report she had someone staying with her that night or the perp showed up after her nightly check in, again knowing him well enough not to call back in. My guess is a family member or someone very close to her is responsible and the RCMP have a very good idea who it is, just not enough proof.
This just dawned on me...perhaps it is totally coincidental, but it wouldn't surprise me if the video holds an important key (indicated in last link on the left site). Here I go again thinking like a criminal...but if it is a family member responsible, who shot the video? It has a time stamp, showing the exact times of when she filled her reports, what time she started her day, her morning routine and when she checked in with her supervisors. It's apparently a video of her daily activities...taken mere weeks before she disappeared. Something is not adding up with this, or it's just my "everyone is a suspect" mentality. Her daily events are all on tape to study...it also allowed the perp to be more familiar with the interior of the cabin. The 44 second video link wouldn't work on that site, but it's stated the video was shown without audio. There is a reason why the video is without audio...it gives too many details away, like the videographers voice and who else was present. I'm looking at family alot closer because of this if I was an investigator.
