The man who triggered Newsweek journalist Kurt Eichenwald's epileptic seizure through Twitter used a prepaid phone with no identifying info. But a little digging revealed that the Tracfone prepaid SIM card he used was once connected to an iCloud account, which ultimately led to his arrest. According to the newly surfaced documents The Verge shared, authorities started by sending a court order to Twitter to ask for the details behind the @jew_goldstein account. If you'll recall, that user sent Eichenwald a "weaponized tweet" containing a strobing image with the words "You deserve a seizure for your posts." The recipient often talks about his condition, so the sender likely knows that the journalist is epileptic.
