Snapchat
It''s interesting that LE has narrowed their focus to the time where BK got into town and that they are using Snapchat to source for any possible unknown BK accounts. Seems like they suspect some throwaway account that they haven't found yet.
Regarding the location of posts requests. A lot of focus has been on YikYak but Snapchat is a much easier to use stalker tool. The Snap Map allows people to see your posting location in real time. And not only that...but if your posts are set to public someone can just click on areas around the Snap Map and see posts from random users and where they are at that moment.
These are some of the featured Snap 3rd party integrations referenced in the warrant...
But I believe Snap's pretty liberal with their API so that list is not exhaustive.
What sticks out to me though is...
Code:
All records pertaining to communications between Snapchat and any person regarding the user or the user’s Snapchat accounts, including contacts with support services, and all records of actions taken, including suspensions of the accounts;
This one is really odd! Are they trying to find out if one of the accounts reported another account for unwanted harassment? Did someone reach out to support and attempt to get more info on a user they came across? This one is probably the most interesting to me. ESPECIALLY when you consider how invasive (even though the user likely doesn't realize it) the Snap Map could be.
