On this appeal Henry J. Askew contended his Sixth Amendment right to a speedy trial was violated in his conviction for filing false federal income tax returns. However, while the appeal was pending, Askew died. Since a criminal prosecution abates ab initio upon the death of an appellant, the case must be remanded with directions to the district court to vacate the judgment and dismiss the indictment.

United States, 9 Cir., 1965, 353 F.2d 327.
