The FBI reportedly found evidence that the Saudi aviation student who killed three American sailors in a shooting at Naval Air Station Pensacola in Florida had been in contact with al Qaeda before carrying out the attack.
Federal officials managed to decrypt an iPhone left at the scene by the shooter, Mohammed Alshamrani. He tried to destroy the phone by shooting it, but investigators managed to get past the encryption and recover the data without the help of Apple, who refused to help the FBI unlock the phone.
Once investigators unlocked the phone, they reportedly found evidence that Alshamrani, a Saudi national who was a 2nd Lieutenant in the Royal Saudi Air Force, had been in contact with at least one member of the terrorist organization in the days before the attack.
The terror group claimed credit for the December 2019 attack, posting an audio recording saying they instructed Alshamrani to shoot up the base. He killed three people and injured eight others during the attack, which lasted about 15 minutes.
