I guess don't bring your phone to a bank robbery.

I believe this is similar to how they nabbed the Washington State University murderer. The feds compelled Amazon to give them all the bluetooth MAC addresses that was seen by the Echo device in the home around the time of the murders and were able to correlate it to other devices their suspect's phone had been visible to.

You should also make sure not to bring your phone to anywhere where a nearby crime is happening because that's all it takes to make you a suspect and force you spend a bunch of money defending yourself. https://www.nbcnews.com/news/us-news/google-tracked-his-bike...

Hopefully rulings like this make that scenario a little less likely to happen, but it doesn't stop it entirely, it just means that the police need to spend 15 minutes to get a rubber-stamped warrant before they turn everyone within a few miles of crime into a suspect.

Source for this? As I recall, his phone was off when he committed the murders. In fact, they used the evidence that it had been turned off just for the duration of the murders (with some padding) against him.

If you're going to commit a crime, don't suddenly turn off your phone if you don't have a history of doing so!

Yes, everyone knows to steal a phone from someone you hate and bring that to the robbery. Right?

Hopeful they used the MAC address to find the phone, then tracked the phone itself, because an IMEI and ICCID are pretty difficult to clone, but a Bluetooth MAC address is trivially easy.

Do you have a source for this? I find it hard to believe this data is persisted, unless they tore open the device to extract logs.

I mean, yeah, I wouldn’t even bring my phone to a legal protest. Or, I’d at least shut it down.
