JUST IN: According to new affadavit from the Providence PD, an anonymous Reddit user (who police would later track down) cracked the case of the Brown/MIT shooter:
Nuh bruh what
Number 15- Burger King Foot Lettuce.
How did it happen? Well, the Brown shooter hadn't removed the Exif data from the uploaded photo, which suggested the culprit was somewhere in Mayfield Heights, Ohio.
