As for the TOD estimates, here's what I recall:
Originally, before the isotope and advanced genetic testing, it was listed as 1977-1985
In the Nov. 2015 press conference, it was narrowed down to 1980-1984 (this was before RE)
I don't recall an official revision with the announcement of RE's discovery during the Jan 2017 press conference. I think it was just assumed that since they left after Thanksgiving, 1981 that the TOD would before that date. If I missed it, someone please holler.
With this latest discovery of him possibly being in NH not until the latter half of 1978 and leaving in late 1981, that would narrow the window down considerably from previous estimates. I don't recall an official revision has been given, but again, if I'm missed it, please let me know.
On a side note, since there is still a gap between 1981-1984 where his whereabouts are still unknown, there is a slim chance that they were still in NH, or the area, just not in Manchester.
