A former staff sergeant stationed at Joint Base Lewis-McChord  pleaded guilty today in U.S. District Court in Tacoma, Wash., to charges related to traveling to a foreign country with the intent to engage in illicit sexual activity with a child, sex trafficking of children, as well as production of child pornography.

Moeun Yoeun, 37, of Steilacoom, Wash., faces a maximum penalty of up to life in prison when he is sentenced by U.S. District Judge Benjamin Settle on Dec. 5.

In his plea agreement, Yoeun admitted to, over the course of several years, using adult and child residents of the Philippines to recruit more than a dozen other children to produce pornography. Yoeun further admitted to traveling to the Philippines and engaging in sexual acts with at least six children in exchange for nominal amounts of money.

Yoeun pleaded guilty to one count of sex trafficking of children, one count of production of child pornography, and one count of engaging in illicit sexual activity in a foreign place. As part of the plea agreement, prosecutors agreed not to charge additional offenses available based on the evidence and moved to dismiss the remaining counts in the indictment.

Other than the 15-year mandatory minimum prison sentence required by law, Judge Settle can impose any sentence op to the maximum penalty of life in prison.  Yoeun will be required to register as a sex offender after he is released from prison and could face federal supervision for the rest of his life.
