Lane, several years ago I asked him if he were interested. He said he would join, but he never did. I once read that cut hair is not really good for DNA testing, but I don't recall the details. Maybe my memory is faulty. If true, however, this may explain why Dr. Sotos' search has been for blood samples and not hair.

Roger, the root of the hair sample must be present to test for nuclear DNA but cut hair can be tested for mitochondrial DNA.

"Can you test hair without the root? Yes. Instead of using nuclear DNA testing, we would use mitochondrial DNA testing. The mitochondrial genome is highly polymorphic or varies greatly from one person to another, making it useful for human identification. Because mitochondrial genes exist in high amounts within a cell they are very useful when analyzing samples that lack nuclear DNA." http://www.forensicdnacenter.com/resourc...tions.html
