3, but was denied. A further appeal was argued before the Fourth Circuit Court of Appeals in February 1992. This appeal listed newly discovered evidence which MacDonald contended was suppressed at his trial and which, he claimed, corroborated his exculpatory account of the murders. This appeal contended that, had Judge Dupree permitted this evidence, the jurors would have learned that all of the doctors hired by the defense, who had worked for the Army, or the government at Walter Reed Hospital, had concluded that MacDonald was psychologically incapable of committing such acts of violence. The court ruled against awarding a new trial on June 2, stating Judge Dupree had acted correctly when he refused to allow the jury to view a transcript of the 1970 Article 32 hearing, and because this was not an insanity trial, he had also acted properly in not allowing the jurors to hear any of the psychiatric testimony. This ruling also stated that Helena Stoeckley's confessions of guilt pertaining to the murders were unreliable and conflicted with the established facts of the case, and accordingly, the judge's ruling against her being allowed to testify at MacDonald's 1979 trial was valid. On September 2, 1997, the district court granted MacDonald's motion to file a supplemental affidavit with the Fourth Circuit Court of Appeals. This affidavit contended that, although several saran fibers found at the crime scene which did not match any evidentiary item recovered had most likely sourced from a doll and not a wig, these fibers were also used in the manufacture of human wigs prior to 1970, and thus added to "the weight of previously amassed exculpatory evidence". His motion for DNA testing upon these fibers was transferred from the Fourth Circuit Court of Appeals to the district court. MacDonald's lawyers were also given the right to pursue DNA tests on limited hair and blood evidence on October 17, 1997. This testing began in December 2000, with MacDonald's lawyers hoping the results would tie Stoeckley and her then-boyfriend, Gregory Mitchell, to the crime scene. On March 10, 2006, the Armed Forces DNA Identification Laboratory announced that the results of this DNA testing revealed that the DNA of neither Stoeckley nor Mitchell matched that upon any of the exhibits tested. Furthermore, although a single hair found within Colette's left palm was also cited by MacDonald as belonging to one of the alleged intruders, this testing
