Now, a year later investigators still can't get into the phone.
Prosecutor Hagan Scotten said the FBI's inability to get into Adams' phone is a "significant wild card," in the case.
The FBI issued a search warrant for Adams' devices in November 2023. Adams initially handed over two phones but didn't have his personal device. The indictment does not mention what type of device Adams uses.
When Adams turned in his mobile the following day, charging documents say, he said he had changed the password a day after learning about the investigation and couldn't remember it.
The indictment alleges that Adams told investigators he changed the password "to prevent members of his staff from inadvertently or intentionally deleting the contents of his phone. "
It does seem a little odd as when the FBI failed to break into the Trump rally shooter's phone in July; they sent the device to the FBI lab in Quantico, Virginia, where agents used an unreleased tool from the Israeli company Cellebrite to crack it in less than an hour.
