JACKSONVILLE, Fla. -- A man known as "John Doe" who was found guilty in May of aggravated identity theft has been sentenced to 10 years in prison, according to a release from the office of U.S. Attorney Robert E. O'Neill.

"John Doe," also known as "L.T.H." and "Leroy" was convicted on seven counts of aggravated identity theft, six counts of falsely representing a social security number, and one count of passport fraud.

Doe was indicted on federal charges in Nov. 2011. Doe was arrested on the federal charges while he was in state custody on fraud charges, according to the release.

Doe assumed the identity of a living victim and had been living under that assumed identity for approximately 22 years, according to court documents and evidence presented during trial.

Using the victim's social security number, he obtained at least 23 government-issued forms of identification. The different forms of identification include a passport, two Mayport Naval Station Military contractor identification cards, three Florida identification cards, and six replacement social security cards.

The Mayport Naval Station identification cards allowed Doe to have unescorted access on at least five different Navy vessels. He also used the victim's personal identification information at JAXPORT to fraudulently obtain a Transportation Worker Identification Credentials badge issued by the Transportation Security Administration.

The case against Doe was prosecuted by Assistant U.S. Attorneys Kathleen O'Malley and Kevin C. Frein. The case was investigated by the FBI, Social Security Administration - Office of the Inspector General, Coast Guard Investigative Services, U.S. Department of State - Diplomatic State Security, Florida Highway Patrol - Bureau of Intelligence and Investigations and the U.S. Customs and Border Protection.
