4th Circuit Excludes Voice Spectographic Analysis

For reasons left somewhat ambiguous by its unpublished opinion, the Fourth Circuit has upheld the trial court's exclusion of a defendant's voice spectography evidence in a criminal case.

See United States v. Ricketts, No. 03-4721 (4th Cir. Dec. 10, 2004) (Niemayer, Williams, & Shedd, JJ.).
