If it were an iPhone 6, how long does a finger print last on a corps? In future crimes is the FBI going to cut fingers off corpses and store them for later use?
Touch ID requires your passcode after 48 hours. So, only if the phone had been previously unlocked with a passcode, kept powered on and charged, and 48 hours had not elapsed, could the government use a corpse fingerprint to unlock.
The device in question is an iPhone 5 and doesn't have a Touch ID sensor, so the question is moot anyway.
