On the iPhone, investigators reviewed photographs, videos, text messages, emails, internet history, app data, location information and other electronically stored evidence believed to be relevant to the investigation.
Warrants were also obtained for records from Verizon Wireless, AT&T, T-Mobile/U.S. Cellular, Facebook, and Snapchat.
The warrants also show investigators’ efforts to determine where people went, who they communicated with, and what digital evidence may have existed in the hours after Watts’ disappearance.
