A Vermont man has been convicted of failing to register as a sex offender in New Hampshire, according to a guilty plea entered in federal court on March 2, 2026.

David Courtemarche, age 45, pleaded guilty to one count of failing to register as a sex offender in U.S. District Court in Concord, New Hampshire, U.S. Attorney Erin Creegan announced.

Courtemarche was convicted in 2003 of sexual assault involving a victim under 16 years of age in Vermont. As a result of this conviction, he was required to register as a sex offender in each state where he resides or is employed, including New Hampshire.

According to the charging documents, Courtemarche began working in New Hampshire in at least August of 2022 and living in the state by at least November 2023. However, he did not register as a sex offender in New Hampshire as required by law.

The charging statute provides for a sentence of up to 10 years in prison, at least 5 years of supervised release, and a fine of $250,000. Sentences are imposed by a federal district court judge based upon the U.S. Sentencing Guidelines and statutes which govern the determination of a sentence in a criminal case.

The United States Marshals Service investigated this case with valuable assistance from the New Hampshire State Police, the Littleton Police Department, and the Lancaster Police Department. Assistant U.S. Attorney Matthew Hunter is prosecuting the case.

This case was brought as part of Project Safe Childhood, a nationwide initiative to combat the growing epidemic of child sexual exploitation and abuse, launched in May 2006 by the Department of Justice. For more information about Project Safe Childhood, please visit https://www.justice.gov/psc.
