Thomas Mark Marceau Sentenced in U.S. District Court

U.S. Attorney’s Office October 24, 2013
  • District of Montana (406) 657-6101

The United States Attorney’s Office announced that during a federal court session in Great Falls, on October 22, 2013, before Chief U.S. District Judge Dana L. Christensen, Thomas Mark Marceau, a 28-year-old resident of Browning and an enrolled member of the Blackfeet Tribe, was sentenced to a term of:

  • Prison: 48 months
  • Special assessment: $200
  • Supervised release: 15 years

Marceau was sentenced in connection with his guilty plea to two counts of abusive sexual contact.

In an offer of proof filed by Assistant U.S. Attorney Ryan G. Weldon, the government stated it would have proved at trial the following:

X.X. disclosed to an FBI agent that Marceau had molested him. The assault occurred sometime between the years of 2007 through 2009, and X.X. was less than 12 years old during the commission of the offense, which occurred within the exterior boundaries of the Blackfeet Indian Reservation. Marceau was in his early 20s.

When interviewed about the sexual assault of X.X., Marceau stated that he was close with X.X. When asked about the inappropriate contact that he had with X.X., Marceau acknowledged that such sexual contact occurred.

Y.Y. was also less than 12 years old when he disclosed to law enforcement that Marceau had molested him. The molestations perpetrated against Y.Y. occurred between 2007 and 2012. As with X.X., Marceau was in his 20s when the molestations against Y.Y. occurred. Y.Y. explained that Marceau had been molesting him since Y.Y. was six years old.

Agents also interviewed Marceau about sexual contact with Y.Y. Marceau admitted that the sexual contact occurred.

Because there is no parole in the federal system, the “truth in sentencing” guidelines mandate that he will likely serve all of the time imposed by the court. In the federal system, he does have the opportunity to earn a sentence reduction for “good behavior.” However, this reduction will not exceed 15 percent of the overall sentence.

The investigation was a cooperative effort between the Federal Bureau of Investigation and the Bureau of Indian Affairs.
