Wichita ? Defense attorneys for a Kansas man accused of participating in the Rwandan genocide have asked a federal judge to acquit their client of all charges.

A court filing Tuesday argues the evidence in the trial of Lazare Kobagaya was insufficient to support a finding of guilt.

Jurors convicted the 84-year-old Topeka man of fraud of an alien registration card, known as a green card, because he lied about his whereabouts during the 1994 genocide. The jury failed to reach a verdict on a second count regarding alleged lies when he applied for citizenship.

The defense argued the guilty verdict should be thrown out because prosecutors only presented evidence of how he got his visa to come into the United States, not how he got his green card.
