Shelton says nothing about 1:22 in his report. The first call would be Kim's from 610, imo. Shelton's report of the incident starts with Kim's call from 610.
This is from Neff's piece in the News & Observer based on the Discovery documents:
"At 1:22 a.m. March 14, Sgt. John Shelton of the Durham Police Department was called to the Kroger supermarket on Hillsborough Road. A scantily clad woman was passed out in a Honda Accord and wouldn't get out of the car. Shelton got no response when he talked loudly to her, his notes on the encounter say."
