I was being generous. I too believe that Callaway got to the scene no more than three to four minutes after hearing the shots.
No need to be generous. I am actually convinced that Callaway got to the scene in a little less than three minutes. The reason why I am convinced is that, some years ago, I actually walked and ran the distance that the killer and Callaway walked and ran and I found I could be done in three minutes. Having said this, you are now talking about a wider subject than when Callaway helped to load Tippit into the ambulance. Let's try to resolve that first, shall we?
Here's the thing... He makes his report on Tippit's squad car radio at 1:19/1:20.
I don't believe for a second that the times on the DPD transcripts are correct, making it erroneous to rely on them for anything. I have an audio recording that starts when Bowley makes his call and ends 4.27 min later. To the best of my knowledge it's a continuous recording. Now, here's the thing; Bowley's call lasted 48 seconds. Exactly 12 seconds later ambulance 602 reports "code 5" confirming it's departure from the funeral home.
According to the official narrative, the Funeral Home received the call for an ambulance at 1:18, but only 20 seconds after 602's code 5 call the DPD dispatcher (who did not call 1:18) calls out "10-4, 603 and 602. 1:19". Now, how is that possible?
If we assume that Bowley started making his call at exactly 1:17:00, the time sequence described above doesn't get us beyond the 1:18:20 mark. However, if Bowley started making his call at around 1:17:40, that would explain the 40 seconds gap, but it would also reduce the time the ambulance had to get to the scene by 40 seconds.
Then, exactly 40 seconds after his initial call the dispatcher calls out "10-4, 605. 1:19", which seems to fit the timeline far better as, according to the actual recording, that second call is made roughly 2 minutes after Bowley started to make his radio call at 1:17. It is however only 6 seconds before Callaway gets on the DPD radio.
So, the first thing we need to resolve is which is the correct 1:19 call. This is important because the 40 seconds between the first and the second call makes all the difference for determining the correct sequence of events, as I will show later on in this discussion. One thing we can safely rule out, based on the actual recordings is, IMO, that Callaway made his call at or after the 1:20 mark.
Do you have an opinion about which 1:19 call is the correct one?
So now that the big show is is over....
This is what I have for the timing of the two "1:19" calls with respect to the Bowley transmission. If I arbitrarily assign the Bowley transmission at +0:00 minutes, then the first "1:19" comes in at +1:16 and he second one comes in at +1:56. The two 1:19 calls are 40 seconds apart. What we can get from this is that it's safe to assume that 1:19:30PM on the dispatchers clock occurred between the two 1:19 timestamps, since the interval between the two timestamps is greater than 30 seconds.
At this point, we consider two cases.
The first is that the first timestamp happened at 1:19:00PM . Then the second one would have occurred at 1:19:40. Therefore, 1:19:30PM would be 10 seconds before the second timestamp in this case. This is the upper limit for 1:19:30.
The second case puts the second timestamp at 1:19:59PM (and we'll round up one second to 1:20:00 just to make things look neater). In this case, the first timestamp would be at 1:19:20PM. In this case, 1:19:30 would be 10 seconds after the first timestamp.
Plugging this back into the Ch 1 recording run time, we get:
+0:00 Hello, police operator....
+1:16 1:19 #1
+1:26 Lower limit for 1:19:30PM
+1:46 Upper limit for 1:19:30PM
+1:56 1:19#2
It's probably better just to say that 1:19:30 occurs at +1:36 +/10 seconds after the beginning of the Bowley call. That would put 1:18:00PM at +0:06 +/- 0:10. Or, the Bowley transmission begins at 1:17:54PM +/- 10 seconds. It could be as early as 1:17:44 and as late as 1:18:04.
Having said that, I should add that Callaway hits the air at +2:12 after the beginning of Bowley's transmission. That would put the Callaway transmission at at 1:20:06PM again +/- 10 seconds.
