The district court erred by failing to grant a mistrial. Error in the following
four respects, viewed in aggregate, deprived Mr. Rentfrow of his Sixth
Amendment right to a fair trial:
1) Failing to limit the number of United States Marshals guarding witness
Brandon Fritts;
2) Failing to cure the prejudice caused by Fritts's testimony regarding his risk
of death, based on his cooperation with the prosecution;
3) Admitting photographs of Mr. Czeck because they lacked probative value
and inflamed the jury; and
4) Failing to dismiss the two jurors who discussed the case and their safety
concerns with each other before deliberations began.
