In a move that may signal another high-stakes clash over encryption, the FBI is asking Apple for help decrypting two iPhones believed to have belonged to Mohammed Saeed Alshamrani, the man suspected of carrying out a shooting attack that killed three people last month at the Naval Air Station in Pensacola, Florida.

The request came in a letter FBI General Counsel Dana Boente sent to her counterpart at Apple on Monday, NBC News reported. Boente said that, although FBI investigators obtained a search warrant to examine the phones, investigators have been unable to guess the passcodes needed to unlock them and decrypt their contents. Complicating matters, 21-year-old Alshamrani fired a round into one of the phones. A second lieutenant in the Saudi Royal Air Force, Alshamrani died in the December 6 shooting. An FBI spokeswoman confirmed the sending of the letter but declined to describe its contents, citing an ongoing investigation.
