A 42-year-old immigrant from Rwanda, who is accused of lying her way into the United States after allegedly participating in the 1994 genocide that left up to 800,000 people dead, is going on trial in a New Hampshire federal court.

Jury selection is set to begin Wednesday in the case of Beatrice Munyenyezi, who allegedly committed fraud in 1995 by denying her alleged involvement in mass rape, murder and kidnappings in Rwanda a year earlier.

Prosecutors allege Munyenyezi, who is now a U.S. citizen, intentionally lied on a refugee questionnaire and naturalization documents about her role in the infamous slaughter, in which ethnic Hutu militants butchered their Tutsi counterparts over a three-month period.

They say Munyenyezi, a Hutu, was a member of an extremist group associated with a paramilitary organization that set up roadblocks and targeted fleeing Tutsis and their sympathizers.

One of the roadblocks was set up outside the Ihuriro Hotel - an establishment owned by her husband's family, according to the indictment.

The mother of three is allegedly married to former militia leader Arsene Shalom Ntahobali, who was convicted of war crimes and sentenced to life in prison last year.
