If she intended to set herself on fire, I don't know why she'd have chosen a day when rain was at all possible, and she'd purchased and brought that umbrella. This rain thing-- I'm looking now and it's overcast like 72% of the time in Bergen at this time of year. She does so much traveling, she has no control over murderers, but she has control over her own suicide, one would think. Why'd it have to be
this day, at
this place? This time of year and this location-- it wasn't the ideal scenario for building a fire. Why the rubber boots? They had hiking boots in 1970, and they had workboots, jmo even the workboots would be preferable. But maybe rubber was what occurred to her, or/and maybe rubber's all she had available. But that sounds more like someone anticipating wet conditions than someone preparing to literally set herself on fire. Tiny amount of petrol beneath her in the soil, and two drops in her hat. That's precious little, but I'm sure the bulk of whatever was used to start the blaze had dried/dissipated, been burned away by then. I know people don't see how she could have transported any petrol to the site, but jmo it actually is possible, in some innocuous container perhaps not even noticed at the scene or not interpreted to be the vessel because she may have brought only a small amount of petrol to start things off, rinsed out residue, and then built a fire with paper & maybe (?) articles of clothing, and then switched to the liquor. (Also, I'd wonder if she didn't have the petrol in some kind of container that burned completely away with the fire itself. I'm looking at Death in Ice Valley, and that is indeed possible per one poster, they're noting a certain type of UK lighter fluid refill made at this time, a sausage-shaped tube that contained a small amount of petrol, and that evidently would completely be burned away) Plus, if she's removing tags/labels from clothing, who's to say she didn't bury the accelerant container?
So there's that half empty bottle of liquor, based on what I can find about the type, I'm seeing 80 proof or potentially above, that will burn steadily if any kind of heat's applied. I'm still not sure how she or the unknown "they" got such a blaze going, but I'm guessing a modest amount of petrol fed with paper and then steady application of liquor, articles of her clothing. Then, there are the pills. She took those in two to three doses. This is where I'd agree with the authorities going with suicide because this does sound like something that someone preparing to essentially build her own pyre might do. The pills served a dual purpose, they would to a large extent numb her, and they'd serve as a backup in case the pyre was not completely successful. Doping her up with pills and taking her out walking-- even to a car-- doesn't sound like a good move for a murderer, but murder still can't be ruled out, as they don't know the timing on her doses and she may have ingested them at the scene over an unknown period of time.
Where was the money coming from for her to live as she traveled? Looking at this, her log:
There are certain letters on here that aren't yet identified. P is Paris. But what are A and L? Guess: She was smuggling heroin that originated through the Golden Triangle (Laos/Thailand/Burma) and A is Amsterdam, L is likely London (maybe Lyon, but more likely London). The most telling notes on here are the July notes where she has "PL" and then "LA" listed for single days. So I think she was going from Paris to London, London to Amsterdam. These were likely big supply points. If she really was Romanian, she and her outfit might also have been working the Balkan route to some extent because Romania is listed as an important point as a transit country on that route, and was largely controlled through Turkish organized crime, I think. And I think "V" is probably Vienna, another major point on the Golden Triangle route.
If the letters really ARE associated with drug smuggling, the odds of murder shoot way, way up in my mind. And the perps would
absolutely want that to look like a suicide. They may have lured her out there thinking they were all ultimately going to be boarding some vessel somewhere, and she feared the worst and left her bags in the locker. TOTAL speculation.
