Beatrice Munyenyezi is serving a 10-year prison sentence after being convicted in 2013.

One of her lawyers, David Ruoff, said Friday they are still mulling their options after the ruling by the three-judge panel, including whether to ask the 1st U.S. Circuit Court of Appeals in Boston for a rehearing by the full court. He said they have been unable to reach Munyenyezi, who is in a federal prison in Alabama, to tell her about the ruling.

Munyenyezi's appeal said the trial judge should not have allowed prosecutors to use her testimony before an international war crimes tribunal to show she had a propensity to lie. Her lawyers accused a prosecutor of making false assertions while cross-examining a defense witness and said there was insufficient evidence to convict her.

Munyenyezi also said her sentence was too harsh. But the appeals court rejected all those arguments Wednesday and said the case record makes for "a bone-chilling read."

Munyenyezi was convicted in February 2013 in the Concord, New Hampshire, federal courthouse where she had been granted U.S. citizenship a decade earlier. Her citizenship was stripped upon her conviction.

The jury found she lied about being affiliated with a political party that orchestrated much of the genocide. Witnesses say she helped patrol one of the notorious checkpoints at which those bearing a card identifying them as Tutsis were singled out for rape and murder.

Italy's highest court overturned the murder conviction against Amanda Knox and her ex-boyfriend Friday over the 2007 slaying of Knox's roommate, bringing to a definitive end the high-profile case that captivated trial-watchers on both sides of the Atlantic.

"Finished!" Knox's lawyer Carlo Dalla Vedova exulted after the decision was read out late Friday. "It couldn't be better than this."

In a rare decision, the supreme Court of Cassation overturned last year's convictions by a Florence appeals court and declined to order another trial. The judges declared that the two did not commit the crime, a stronger exoneration than merely finding that there wasn't enough evidence to convict.

In a statement issued from her home in Seattle, Knox said she was "relieved and grateful" for the decision.

"The knowledge of my innocence has given me strength in the darkest times of this ordeal," she said, thanking her supporters for believing in her.

Experts have said such a complete exoneration is unusual for the high court, which could have upheld the conviction or ordered a new trial as it did in 2011 when the case first came up to its review on appeal.

The justices' reasoning will be released within 90 days.

The decision ends the long legal battle waged by Knox and Italian co-defendant Raffaele Sollecito to clear their names in the death of British student Meredith Kercher, after they spent nearly four years in prison immediately after the murder.
