These are the consolidated appeals of defendants Gary Edward Aexander, Jonathan Harrington, Anthony F.- Hicks and Willie James Harris. The defendants appeal their convictions for conspiracy to commit robbery, in violation of 18 U.S.C. § 371 ; armed bank robbery, in violation of 18 U.S.C. § 2113 (a) and (d); and use of a firearm during commission of a crime of violence, in violation of 18 U.S.C. § 924 (c).

The defendants contend their Sixth Amendment right to trial by an impartial jury was violated because the district court (1) failed to strike for cause two prospective jurors who had previously been victims of robbery, and, (2) replaced a juror with an alternate on the last day of trial when the juror’s child became ill and had to be taken *1482 to a hospital. They also argue the district court committed reversible error by admitting the government’s FDIC “Certificate of Proof of Insured Status.” as evidence that the victim bank was federally insured at the time of the robbery. In addition, defendant Hicks seeks reversal of his conviction on the ground that the district court erroneously admitted, for impeachment purposes, evidence of his prior drug and robbery convictions.…
