I observe the wording. The summary says that samples from 7 (the panties), 14L and 14M (the left and right hand nails) revealed a mixture (see the word "mix-" which leads to the off-screen completion "-ture"?). But look further. "IF the minor" component in the samples from 7, 14L and 14M "were contributed by a single" individual, then the Ramseys can be excluded. But we are all smart enough to fill in that particular blank. If the minor component in the samples from 7, 14L and 14M were contributed by more than a single individual, then the Ramseys are not excluded, not by this summary, in any case. If both John's and Patsy's DNA are under JonBenet's nails, they may well be included because neither individually has the same markers as all components of the sample, but together they may add up to the components found.
