The first-degree murder trial of Ronald Spaulding was postposed Monday after a defense attorney filed a last-minute motion to have key evidence tossed out. The trial was reset for March 24. Spaulding, 24, is one of three defendants indicted in connection with the August 2000 shooting death of Robert Dean in Holiday. On Monday morning, just as jury selection was to begin, defense attorney Charles Lykes filed several motions, including one asking a judge to throw out Spaulding's statement to detectives. That motion is scheduled for a hearing this morning. Spaulding, who told detectives that he took part in the botched robbery that resulted in Dean's death, faces the possibility of life in prison.
