A grand jury has decided against charging NASCAR star Tony Stewart in the August death of another driver at a sprint car race in upstate New York. The decision was announced nearly seven weeks after Stewart’s car struck and killed Kevin Ward Jr. at a dirt-track race on Aug. 9. Ward had climbed from his car after it had spun while racing alongside Stewart. The 20-year-old walked down the track, waving his arms in an apparent attempt to confront the three-time NASCAR champion. Ward died of blunt force trauma. Stewart skipped three races following what he called a tragic accident.
