Who knows. Especially with this task force.
It can be difficult to sequence dna because of the 23 chromosomes pairs only one will tell the sex. And women have two x and men have one x. So you will show x 75% of the time. If you have a complete pair you will know if it is male or female but if you have an incomplete pair you will not be able to tell. You can sequence each individual pair to determine if there are two separate xs in the sequence but that is very expensive and laborious.
So I am thinking it likely they had DNA they couldn't sequence easily of which one showed easily male. That is the one they are making a big deal of.
Also these samples were not CODiS applicable which tells me they didn't have the proper amount of markers to be submitted to begin with meaning they were incomplete sequences.
DNA analysis is way above my pay grade, but thanks for explaining. I think I get it! JMO
