CE705 has Sheriff Decker's transcript, a fragmentary document with few messages. The sheriff's dispatcher's exchange with #109 reflects the enigmatic DPD channel 1 dispatch "Attention. Signal 19, police officer, 510 East Jefferson" [Kimbrough/Shearer #914]. The following transcript includes an interpolation from CE705 (in bold).
898. CITIZEN: Hello, police operator?
899. DIS: Go ahead. Go ahead, citizen using the police radio.
900. CITIZEN: There's been a shooting out here.
901. DIS: Where's it at?
902. DIS: The citizen using the police radio...
903. CITIZEN: Tenth Street.
904. DIS: What location on Tenth Street?
905. CITIZEN: Between Marsalis and Beckley. It's a police officer. Somebody shot him. What--what's...404 Tenth Street.
906. DIS: Can you hear me?
907. (Man and woman's voice in background)
908. DIS: 78.
909. CITIZEN: It's a police car, number 10.
910. DIS: 78.
911. DIS: (?) 78.
912. CITIZEN: Got that?
913. CITIZEN: Hello, police operator. Did you get that? (Some other unknown voice came in with "a police officer, 510 E. Jefferson")
914. DIS: Attention. Signal 19, police officer, 510 East Jefferson.
Without the interpolated "a police officer, 510 E. Jefferson" the transcript's Signal 19 direction to an address that had not been received makes no sense at all. Even so, why dispatch to 510 East Jefferson immediately after Bowley transmitted the correct address?
And why 510 E. Jefferson, the location of a used car lot? Answer -- it was close to the library where Decker's men (deputies & constables) gathered in force long before DPD's C.T. Walker showed up.
It was a trap, of course, almost sprung on terrified library employee Adrian Hamby.
