What ever happened to the female J6 bombing suspect?

7. I'm not sure whether cell data is kept forever

but cell towers need to know when a cellphone enters into its cell area. The cellphone sends a micro-signal alerting the tower that, "Hey, it's me, 408-323-0913" (rather, it's probably the SIM ID number, but you get the idea).

At any given time, and especially in a densely populated place like DC, there would be upwards of 10,000 phones within a single cell coverage area. Those phones just have to tell the cell tower that they're in that cell's coverage area. The tower would then relay that information to the "home switchboard" for the cellphone to tell it to send any calls to that cell tower.

The thing is, the person seems to have walk through multiple cell areas. If the person had the phone on to communicate with the cell towers, then the towers would have a record of that phone number being there at around that time. That's assuming also that such records are kept. But if such records are kept, they can see which mobile number is common at those locations at those times.
