About
Autosomal DNA testing was below the limit of detection, and the shaft was transferred for mitochondrial DNA analysis. The hair's mitochondrial profile was consistent with O'Keefe's known standard; neither O'Keefe nor his maternal relatives could be excluded as possible sources. Separately, the expert testified that, with 95% confidence, at least 99.895% of the population could be excluded as a source of the hair sample.
