Beware When They Claim a "DNA Match"

Not with any case particularly, but in general, not all DNA tests are equal. They depend on suspect samples which may not be of high quality. If you have no other evidence, they should not be automatically considered as a gold standard in determining guilt beyond a reasonable doubt. Autosomal DNA is dependent on how many loci are found. The FBI tests and records 13 loci. Suspect samples may have 13, 10, 8, 5, or only one loci that show up. The fewer the loci, the more the matches.
