The hearings were the first court appearances for the two men since the mid-summer search for the missing men and the discovery of their buried remains riveted the region. DiNardo and Kratz have been jailed without bail since their arrests, and now await formal arraignment on the charges next month. Prosecutors have not disclosed a motive for the murders, and say they may never find one. Still, the proceedings also drew dozens of relatives of the victims, who filled three rows in the courtroom.
