Considering the extensive search and its lack of evidence, I have been strongly considering abduction as a possibility. The innkeepers comments about a possible kidnapping are quite strange.
I know this will sound farfetched, but Patti has an interesting background. She’s of Taiwanese origin and her background is in engineering. She recently retired from a company that merged with Raytheon around the time of her retirement. She worked there for over a decade. The company develops technologies related to aerospace and military manufacturing and trade compliance, amongst other things. There also seems to have been a scandal with the company a few years ago when they were caught selling military technologies to China.
What I am getting at—there has been a history of kidnapping in Japan by North Korea to teach English and Japanese and other technical knowledge to their citizens. This was done easily by boat across the Sea of Japan. It’s not spoken about much anymore, but I have no doubt it still continues unreported given the ongoing tensions. Given her past company’s relations with China, this could have even been a bad actor within Japan.
With Patti’s background as an engineer in military manufacturing and trade, a Taiwanese national, and an older woman traveling alone in a remote area, she could very well be an attractive target, whether planned (social media stalking? Passport alert?) or a crime of opportunity (speaking about her past to the wrong person at a hostel).
I don’t doubt that this hasn’t crossed her family’s minds given their early concerns about foul play, and the fact that the FBI was apparently involved very early on. It’s a terrifying thought regardless.
If there have been any concerns about this, I would imagine there’s been resistance from all sides to make mention of it in the media to avoid stirring the pot as far as relations go. It seems it would be difficult to point the finger at anyone, yet also seems like a noteworthy data point of why kidnapping is certainly plausible. Tensions across Asia have been pretty high for a while now.
Lastly, given the sensitivity of her background, I am sure it’s relevant to why the police are being less than helpful to share any phone data they have. This opens up a can of worms that would be revealing of Japan’s surveillance technologies. There is always sensitivity between nations sharing data and technology, and the U.S. still to this day have military bases in Japan.
