Something I was wondering about in this case ... They tracked the killer through his use of burner phones 10 years ago.

And I obviously know phones continuously ping cell towers.

So that means somewhere out there, there's a database of all cell phones and their locations for all time, with fine-grained resolution? They don't ever delete it, at least not in the last 10 years?

Or it's 1 database per cell provider ? I guess phones ping towers that are not owned by the company that provided the phone

I'd be curious if anyone has a link to a good summary of how this works, and the location tracking implications. Do they have to do a subpoena, or is it just a big database everyone's doing joins against? What's the resolution of the data?

I knew that people obviously get caught due to cell phone tracking -- it comes up in every one of these cases, like the Idaho killer recently. But I'm slightly surprised they reached back 10 years and did it

You get some insight into it if you carefully read Mahoun’s blog about looking for Bill Ewasko.

This?

Bombcar, my good HN buddy, it'd be great if you included the link rather than a few keywords. I've never heard of any of these people before. Additionally, lots of people won't bother to search and won't ever see the cool, interesting thing. Unless that's your intent.. ;)

Wow, that was fascinating. Reminded me of the search for MH370.

Now that I'm at computer I can note that Bill was found: https://youtu.be/2J9wsJb8P1Y

Thanks! Sorry to be that guy, but is there a text write-up of the conclusion you’d recommend? I searched and came across some local news articles and Reddit posts but nothing as detailed as the blog you mentioned (which surprised me that it didn’t have an update including the discovery).

The bones were found in a very strange location "the last place you'd look" and it didn't make sense why he'd end up there - the video provides (during a walk to where the remains were found) about "how would an experienced hiker end up like this" and basically lays out how each step of the journey "made sense" and the last attempt was based on a relatively low detail map - he was heading cross-country to try to get to a road in the shortest distance possible.

It also drives home how you should not deviate from planned travel and always try to back track, but I digress.
