Can a juror whose children have been convicted of drug-related crimes be found to have bias?

214 F.3d at 1113. We held that the juror's equivocal statements regarding her ability to be impartial, coupled with "the similarity between her traumatic familial experience and the defendant's alleged conduct," warranted reversal of the defendant's conviction "under either an express or implied bias theory." Id. at 1114; see also United States v. Eubanks, 591 F.2d 513, 517 (9th Cir.1979) (per curiam) (presuming bias in a heroin conspiracy case on the part of a juror whose children were in prison for heroin-related crimes); United States v. Allsup, 566 F.2d 68, 71-72 (9th Cir.1977) (holding that bias may be presumed from the "potential for substantial emotional involvement" inherent where prospective jurors worked for a bank, which had a branch that defendants were charged with robbing).
