A US appeals court has ordered an investigation into potential juror bias in the case of the Boston Marathon bomber. The court's decision comes after defense attorneys argued that one of the jurors who sentenced Dzhokhar Tsarnaev to death had not been truthful during the jury selection process.
The appeals court directed the district court to examine whether the juror's alleged bias affected Tsarnaev's right to a fair trial. The defense team claimed that the juror had failed to disclose certain information about his social media activity and interactions that could have influenced his impartiality.
