The article doesn't say so, but some web search and deepl.com translation makes it sound like the second missing person may have died by suicide. When they first found the sunken car, they wondered (presuming that the car had gone off the road by accident) how the heck the car had ended up so far out into the water. The answer might be that it didn't fall off the road, but rather was driven off at high speed on purpose, with the express intention of making it hard to find afterwards. :(

I liked how they used logic to narrow things down to just what was verifiable and only ended up searching a few spots in the end. It makes me feel like the police should work with them to solve other missing persons cases.

Yeah it's first principles reasoning, just like coding and manufacturing lol!

>The taxi driver later said that there wasn’t anything unusual about Juha or his behavior. He just seemed to have sat in an uncomfortable manner, like he had hurt his back. He also said Juha might have been a bit tipsy.

Perhaps intoxication + a muscle spasm caused him to floor the gas at some point? Maybe his leg fell asleep while driving?
