INDIANAPOLIS (AP) — A former Indianapolis police officer filed an appeal Wednesday challenging his convictions for killing one motorcyclist and seriously injuring two others while driving drunk in his police cruiser. A brief filed by public defenders representing David Bisard claims Allen Superior Court Judge John Surbeck should have declared a mistrial after a juror violated the judge's orders by conducting Internet research on the case and reported the findings to other jurors, WRTV-TV reported (http://bit.ly/1nVRDha). The appeal said a third area of concern was Bisard being denied his due process right to present a defense when prosecutors presented expert testimony about what it meant to be a "tolerant drinker."
