 Both have been sent to the FBI lab in Quantico, Virginia, for analysis. Now, the FBI says the gun was purchased legally, it believes, by the shooter's father. Rojek identified it as an AR-556, which is an AR-15-style rifle. The cell phone, though, to your question, is an urgent focus for investigators. The FBI has the phone, but as of yesterday afternoon, hadn't been able to crack into it to get access to its contents. And doing that, of course, would likely reveal a ton of information about Rojek.
