As noted before, cell phone data is going to screw these bozos. One of the most sought after clowns is the woman known as “bull horn lady.” This photo (a screen grab from a video shot outside the capitol) shows her holding a phone. Based on the camera placement, it may be a 2019 iPhone 11.
Positively identifying the phone would be useful for the following reason:
It would allow the investigators sifting through the cell phone tower data to filter out most of the phones in the area at the time.
Working with a greatly reduced dataset, it would be relatively straightforward to tag each of the remaining cell phones to a geographic region based on billing information. All carriers know which model phone you are using with a given SIM card.
Once you have a set of targets, you filter on phone numbers registered to women.
Then you pull up driver license records.
To put the numbers in perspective:
Estimates of the total crowd size ranged from tens of thousands to thirty thousand. Assuming that several thousand were near the tunnel at 5 pm (when this video was shot), you would likely have to search less than a thousand total records as iPhones are only about 15% of the total US market. After a couple more filtering steps (check phone models, check owners, check photo ids) If you have a targeted list of a hundred candidates, I would be surprised.
If you can positively identify the phone model, drop me a note in the comments. Thanks.
