PHOENIX—Defense attorneys for Thomas David Skrepnak, accused in 1999 of fatally stabbing all 12 members of the jury hearing his armed-robbery trial, are having trouble finding unbiased jurors for his upcoming murder trial. "It is difficult to find a jury that won't be at least somewhat prejudiced against Thomas," lead defense attorney Patricia Wynne said Monday, "especially given the hot-button issue of jury murder at hand here." Skrepnak's last six court appearances all ended in mistrial.
