Is the hair in fact red? I've seen claims of such, but never anything in the documentation to corroborate them. Regardless, the color of a particular hair doesn't rule out the possibility that it grew out of someone whose hairs are typically a very different color. So even if the hair is actually brown or blonde, it still may well be Terry Hobbs'. It could also be his brother's, his mother's or anyone else who share the same maternal linage as him, which Thomas Fedor estimated at 1.5% of the population. In the same regards, any of the hairs consistent with mDNA of any of the boys could in fact be hairs from their respective siblings, mothers, or millions of other people who share their same respective mDNA profiles.
