An independent autopsy commissioned by the family of Nolan Xavier Wells has deepened the mystery surrounding the 18-year-old's death, concluding that both the cause and manner of death remain "undetermined" pending further investigation.
Civil rights attorney Ben Crump, who represents Wells' family, revealed the preliminary findings Wednesday before a standing-room-only audience at the NAACP National Convention in Chicago, where the announcement drew audible gasps from the crowd.
