The DNA testing has had many 'false starts,' inconclusive results etc. etc. etc.
They have had a tortured time of it learning to get clean DNA evidence material uncontaminated by handling the skulls etc. etc.
Nevertheless, I think that L.A. Marzullli & associates are on the right trail and coming up with the most plausible conclusions accordingly.
It's a messy scene from many perspectives for many reasons. I do think that Marzulli's conclusions, at their core, are likely to turn out being very accurate.
I think the debunkers are mostly "True anti-believers" and as such seize on this or that flaw in the process; this or that rationalization etc. and avoid the whole picture as well as significant contra-indications to their assumptions and blather.
