FBI finds cellphone evidence linking al Qaeda to gunman in deadly shooting at Florida naval base

The FBI has found cellphone evidence linking al Qaeda to the deadly terror attack at a Florida naval base last December. 

Investigators uncovered the ties by breaking through the encryption protecting two iPhones used by Mohammed Alshamrani, the Saudi military trainee who opened fire on the Naval Air Base Station in Pensacola, killing three US sailors and injuring eight other people before he was shot dead by law enforcement.

Officials briefed on the matter said that Alshamrani had been in contact with an al Qaeda operative prior to the shooting.  

Attorney General William Barr and FBI Director Chris Wray announced the finding at a news conference on Monday. 

The Justice Department had asked Apple in January to help extract data from Alshamrani’s iPhones, including one that authorities say Alshamrani damaged with a bullet after being confronted by law enforcement.

On Monday Barr said that Apple would not help investigators unlock the phones, saying they were ‘deliberately designed so only the user, in this case the terrorist, could gain access to their contents’.  

‘Today I am pleased to announce that thanks to the relentless efforts and ingenuity of FBI technicians, the FBI finally succeeded in unlocking Alshamrani’s phones,’ Barr said.  

‘The phones contained information previously unknown to us that definitively establishes Alshamrani’s significant ties to al Qaeda in the Arabian Peninsula – not only before the attack, but before he even arrived in the United States.

‘We now have a clearer understanding of Alshamrani’s associations and activities in the years, months and days leading up to his attack.’  

Barr said the information in the phone has ‘already proved invaluable in protecting the American people’, noting that the US recently conducted an attack targeting one of Alshamrani’s associates in Yemen.

 He then turned the podium over to Wray, who praised the ‘vital’ work of his investigators at the FBI.

‘The evidence we’ve been able to develop in from the killer’s devices shows the Pensacola attack was the brutal culmination of years of planning and preparation my a longtime AQAP associate,’ Wray said.

Law enforcement officials had left no doubt that Alshamrani was motivated by jihadist ideology, saying he visited a New York City memorial to the attacks of September 11, 2001, over the Thanksgiving holiday weekend and posted anti-American and anti-Israeli messages on social media just two hours before the shooting.

Separately, al-Qaeda’s branch in Yemen, released a video claiming responsibility for the attack. 

The branch, al-Qaeda in the Arabian Peninsula, or AQAP, has long been considered the global network’s most dangerous branch and has attempted to carry out attacks on the US mainland.

In January, US officials announced that they were sending home 21 Saudi military students after an investigation revealed that they had had jihadist or anti-American sentiments on social media pages or had ‘contact with child pornography.’

Barr said at the time that Saudi Arabia had agreed to review the conduct of all 21 to see if they should face military discipline and to send back anyone the US later determines should face charges.

Barr and Wray took aim directly at Apple for not helping FBI investigators break the encryption during Monday’s press conference.  

Wray said that the challenge FBI technicians faced in unlocking the phones ‘is hard to overstate’. 

‘We received effectively no help from Apple. We canvassed every partner and company out there that may have had a solution, but none did, so we did it ourselves,’ he said.

FBI Director Chris Wray said Apple 'seriously hampered this investigation' by refusing to help agents crack Alshamrani's phones

‘Unfortunately, the technique that we developed is not a fix for our broader Apple problem – but it has made a huge difference in this investigation. 

‘While we’re thanking FBI technicians, we should also be thinking about the cost of all that work. 

‘Public servants already swamped with important things to do to protect the American people had to spend all that time just to access evidence that we had court-authorized search warrants for months ago. 

Wray went on to say that the delay in accessing the devices ‘seriously hampered this investigation’.  

‘Finally getting our hands on the evidence Alshamrani tried to keep from us is great – but we really needed it months ago, back in December,’ he said.

He noted that anyone Alshamrani spoke to before the attack has now had months to ‘concoct and compare stories with co-conspirators, destroy evidence, and disappear’.

‘As a result, there’s a lot we can’t do at this point that we could have done months ago,’ Wray said.
