beach. i ve been there. it s a very difficult area for k-9 units or police investigators to go through. it s not people don t walk around there, it s rather desolate. that doesn t surprise me. what surprises me is that so many years have elapsed with so little progress. and people are fearful that there s a serial killer in their midst. what are we going to do? and the police aren t doing anything, i think that s what stands out in my mind. so now that and, obviously there were mistakes as we pointed out. then they reinvigorated the investigation. we now know it s in three states that they re looking. we know that there are additional bodies have been found at gilgo beach. we don t know if he s involved. we don t know if there are many more. do you think that it s possible that they are able to tie heuermann at this point to many more murders? i think it s very possible, because heuermann s dna profile is now on codus, this national
dna profile which is very fortunate but it isn t the type of numbers that we re all accustomed to hearing in court. trace: and i m wondering if you think this will lead to them using igg or investigative genetic genealogy. is there enough to use that? is that feasible in this scenario, cc? you know, we don t know if they did ploy investigative genetic genealogy to help identify him. the da declined to reveal all of the dna evidence at the press conference. now, they certainly could have, and that is because technology has advanced to such a degree that we can use rootless hair to perform investigative genetic genealogy. so we don t know if this hair had a root on it but i m suspecting it may not have which is why they turned to midochondrial dna in their investigation but they certainly have used investigative genetic

time, hair was subsequently submitted for further dna analysis, and in july 2020 they had a dna profile of the hair, and then enter the pizza slice, and then they are connecting the dna from the two and they have found a match. yes, back when the murders happened, dna technology is not what it was and since between, when that happened to where we are now, it s moved so fast and so detectives had to be along all this time careful about consumption. talk about consumption for a minute. you have a single hair. test every time you test it you lose a part of the evidence you have and you worry about consuming all that evidence when you know that technology is getting better and better. if it was if technology was that good ten years ago, imagine what it s going to be ten more years from now to have it. what we are missing here, how did they know to good to him to
