The principle "witness" produced by Bragalia is Sterling Colgate. As to Colgate's motives in declaring it a "hoax", Ray Stanford's observations on theparacast.com the other day are highly relevant.
It turns out Colgate was declaring the whole incident a hoax to reporters within only days of the incident. When pressed by reporters why it was a hoax, Colgate answered that he knew as an astrophysicist that interstellar travel was impossible, therefore it couldn't have been an alien craft, therefore it must have been a hoax perpetrated by his own students.
When pressed further about which students were involved, Colgate said he suspected one student in particular.
Colgate is still telling the same vague story. He made up the whole hoax claim in his own mind and attributed it to his students because he is one of these "scientific" skeptibunker types who thinks he can determine from first principles that alien visitation is impossible. (In reality, this is about as unscientific a statement as one can make.)
So it seems that what we have here is a "witness" who didn't investigate, doesn't really know anything, and made up the whole hoax claim, including the alleged students because of a personal belief system. Colgate won't name the alleged student perpetrators because they never existed. He can't provide details of how the "hoax" was carried out, because there was no hoax. He never _knew_ anything, only _believed_ that it must be a hoax and his students were behind it.
Bragalia will never hear back from Colgate with names of the students and details of how they carried it out because there is nothing there.
The bottom line is Colgate's hoax claim is itself a hoax.
