Idaho prosecutors have served warrants to over 60 companies as part of their investigation into the stabbing deaths of four University of Idaho students.
Brian Coburger has been charged with the murders, but his motive remains unknown.
The recently released more than 700 pages of search warrants, which had been previously sealed, shed little light on the case as many details have been redacted.
In December, search warrants were sent to retail companies such as Amazon, eBay, and Walmart, requesting a list of anyone who bought a K-bar knife or knife sheath.
Social media companies, including Tinder, Facebook Meta, and Yik Yak, were also served with warrants, as were banks.
The full picture of what the police obtained with these new warrants remains unknown, but some information may be revealed at a preliminary hearing scheduled for June.
