JACKSONVILLE, Fla. (AP) -- John Doe has been sentenced to 10 years in prison for aggravated identity theft and fraud charges.
Federal authorities announced Monday they haven't been able to "affirmatively" identify him. Doe was convicted in May of seven counts of aggravated identity theft, six counts of falsely representing a social security number and one count of passport fraud.
Authorities say he used someone else's identity for more than 20 years and was able to obtain at least 23 government issued forms of identification in the victim's name. They included two Mayport Naval Station Military Contractor identification cards, giving him access to at least five different Navy vessels.
John Doe also used the victim's personal information at the Jacksonville Port Authority to obtain a badge issued by the Transportation Security Administration.
