 The FBI special agent leading the investigation, Kevin Rojek, says they have recovered the shooter's gun and cell phone. Both items are being sent to the FBI lab in Quantico, Virginia, for analysis. Rojek says the bureau still has not been able to open the phone to access its contents, but is working to do so. He confirmed that the weapon used was an AR-style 5.56 rifle that had been purchased legally, the FBI believes, by Crook's father.
