Yes, I did day "if I remember correctly" regarding Frazier's sixth floor museum interview. I remembered incorrectly and placed that statement in the wrong interview. But Frazier does say that way back in 2002.
Anyway, O.V. Campbell's statement shortly after the assassination (11/24/63) appears to support Frazier's statement in the 2002 interview. Here is what Campbell said:
Inside he was told shortly thereafter by the warehouse superintendent, Mr. TRULY, that all the employees of the company had been rounded up and one employee, LEE HARVEY OSWALD, was missing.

I seem to remember reading that one of the investigators had requested to know of any missing employees. But I haven't been able to remember exactly who requested this. So, it appears reasonable to me that the request would get communicated and that the different companies in that building would have their own individual roll calls. And that any missing employees would be reported.
Point out in Truly's testimony where he rounds up all the employees of the company.
Conveniently it's been recently posted.
And note that Campbell is one of the people Truly confers with when he makes his decision that Oswald is missing.
" I didn't know whether they were all there or not." - Roy Truly
Did Truly tell Campbell the same lie, the same lie he told Lumpkin and then Fritz and his men? Note what Campbell says -
he was told by Truly he had rounded up all the employees.
Thank you for further corroboration that Truly was telling the same lie to different people.
LATER EDIT:
In his testimony Truly says this at the moment he decides Oswald is missing:
So I picked up the telephone and called Mr. Aiken down at the other warehouse who keeps our application blanks. Back up there.
First I mentioned to Mr. Campbell--I asked Bill Shelley if he had seen him, he looked around and said no.Note he says - "First I mentioned to Mr. Campbell" - and then suddenly cuts himself off and changes the subject to Shelley.
Could this be the moment he told Campbell that he'd rounded up all the employees and Oswald was missing but then realised he shouldn't be saying that in his testimony?
