Well I am sure that the answer to this lies somewhere deep in the pages of this forum, but forgive me for asking, but I just cant look through all of it to find the correct answer, (if there is one?). What happened to the damn cigarette butts from the ones he smoked? They could not have known it in 1971 just how valuable they could have been. Not sure if the DNA would still be intact but I imagine if its intact on a 10,000 year old Mammoth then it might have been? I wonder if they were simply tossed? And the DNA that exists on the tie, was it ever compared to the 5 top suspects who are deceased? Like Reca for instance? Go easy.
Who is this THEY you people keep throwing around? The average FBI agent walking the streets? Forensic people at Washington? Forensic people in crime labs all over the world in 1971? Cooper fan kids Bruce Smith, Galen Cook, Shutter, RMB, Geoff Gray, etal in 1971 ......... ?
Serological forensics had been in forensic labs for a long time by 1971. Frederick Sanger developed a DNA sequencing technique for sequencing the first full genome of a virus called phiX174, in 1975/77 with the groundwork for that building since the 1950s! We had prints and print chemistry, serological testing, a vast knowledge concerning immune markers being assembled (out of kidney transplant research ..), micro neuron chemistry studies in every branch of anatomical medicine (an area I worked in in 69), ...... it was obvious to anyone in any area of forensics in 1971 and to educated people generally that the value of biological evidence was important and exploding monthly! You could not become an FBI agent in 1971 without being told that in your training! Many agents had law degrees!
The issue of the cigarette butts was probably a clerical issue. I seriously doubt Right Wing Fascist FBI zombies failed to realise the butts weren't important, in1971
