The Tippit Case in the New Millenium

[Milo Reech]

The eventual "a police officer, 510 E. Jefferson" follows at 41:29 but the dispatcher's "Attention. Signal 19, police officer, 510 East Jefferson" is missing

This is where we conflict Milo... I only hear one instance of "510 E Jefferson" at 41:29 in response to Bowley asking "did you get that?"
After Dispatch says "what location on 10th St" we get voices and someone says "404 10th"

What I do not hear is the "ATTENTION. Signal 19" part of that statement... but then "Did you get that" is said over the beginning of the Dispatcher's sentence

Right -- you won't hear "Attention. Signal 19, police officer, 510 East Jefferson" in the audio because it is missing from this defective recording (poor quality, fragmentary, many gaps). It's not there, likewise absent from CE 705, although the Shearer, Sawyer A & CE 1974 transcripts all have it.

Your transcript has "Attention. Signal 19, police officer, 510 East Jefferson" at line 855. Preceding line 854 is incomplete. The second part following Bowley's "Did you get that?" is missing (absent). It is "A police officer, 510 East Jefferson," heard at 41:29 of the recording, also heard in c-span's Cronkite documentary, a second voice sudden & strong, not Bowley's.

Here's how the sequence should read:
854 -- Hello, police operator. Did you get that? A police officer, 510 East Jefferson.
855 -- Attention. Signal 19, police officer, 510 East Jefferson.

The address "510 East Jefferson" should appear in both 854 & 855.
