Illegal immigrant from French Guiana pleads guilty after stealing the identities of two victims

ALEXANDRIA, Va. - A national of French Guiana residing illegally in Adelphi, Maryland, pled guilty today to aggravated identity theft, Social Security fraud, and use of a passport secured by false statements.

According to court documents, Jean Claude Casimir, 59, was deported from the United States on June 7, 1995, and Sept. 8, 2007. Following his latest removal, Casimir illegally re-entered the United States.

In 2010 and again in 2021, Casimir used the identity of another person, identified as "V1," to obtain a U.S. passport. Casimir used the unlawfully acquired U.S. passport that he obtained in V1's identity in 2021 to travel and pass through security at Washington Dulles International Airport in 2022. On May 26, 2022, Casimir used the social security number of another victim, a minor identified as "V2," at the Virginia Department of Motor Vehicles in Alexandria to obtain a vehicle title and registration.

Casimir also used the personal identifiable information of the two victims to open financial accounts, obtain loans, and for other purposes. On June 1, 2022, Casimir used the alias "Duke Casimir" and the social security number of V2 to obtain a vehicle loan through a credit union, which caused a reported loss to the credit union of $30,394.68. On May 19, 2025, V1 informed the credit union that an account was opened with his identity and without his permission, and the credit union reported an additional loss of $16,228.81.

On Oct. 2, 2024, Casimir opened a checking and savings account with a bank using V1's identity information. On Sept. 8, 2025, Casimir began using a credit card from that bank under V1's identity information. The amount owed for that card is $5,229.72. On March 2, 2026, Casimir used V1's social security number on a Virginia DMV "Power of Attorney" form, and on March 3, used V1's identity information to purchase a vehicle for $84,186. Casimir also filed taxes in the name of V1 and claimed earnings of $87,646 for tax year 2025, causing V1 financial problems.

Casimir is scheduled to be sentenced on Nov. 24 and faces a mandatory minimum of two years and up to 15 years in prison and full restitution. A federal district court judge will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors.
