Was 1:22 am the time on Shelton's report?
Was that the time he responded or got the call?
If so, I can see them correlating that time, she does say APPROXIMATELY.
She says she RESPONDED to DUKE Emergency at Approximately 1:22 am. Does Responded mean arrive?
I'm thinking she checked the time with Shelton (the Case Officer) and filled the time in at the hospital later.
