FBI to help Arkansas prosecutor in unlocking murder suspect's iPhone

The phone belongs to teenage suspect Hunter Drexler, and the announcement comes just days FBI says it gained access to the San Bernardino gunman's iPhone

The FBI agreed to help an Arkansas prosecutor unlock an iPhone and iPod belonging to two teenagers accused of killing a couple, just days after the federal agency announced it had gained access to an iPhone linked to the San Bernardino gunman.

The FBI announced Monday that it had gained access to an iPhone belonging to Syed Farook, who died with his wife in a gun battle with police after they killed 14 people in San Bernardino in December. The FBI hasn't revealed how it cracked Farook's iPhone. Authorities also haven't said whether the iPhone and iPod in the Arkansas case are the same models or whether the FBI will use the same method to try to get into the devices.
