The effort to retard the bus time was an act of futility anyway. Markham would not have waited at the corner of Patton & Tenth at 1:15 to catch a bus that stopped at Jefferson at that time. Whatever her mental shortcomings no one declared her incapable of catching a bus, an endeavor she accomplished on a twice daily basis.
The DPD radio logs also have timing problems, mainly due to unsynchronized clocks that showed different times according to the height of the observer. Not joking, this is described in the first two pages of CE1974 with the upshot that the timestamps were subject to an inaccuracy of at least two minutes. So much for CE705's 1:08 transmissions attributed to 78 (Tippit).
The content is far more deserving of scrutiny. For example, this wonky disconnect between location information received by the dispatcher and the location he transmitted:
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?
914. DIS: Attention. Signal 19, police officer, 510 East Jefferson.

The Sheriff's dispatcher fixed on the inexplicable signal 19 address to the exclusion of several other addresses radioed by DPD, sending everyone to 510 East Jefferson (close to the library) long before DPD Officer C.T. Walker spotted the page running across the library lawn.
