Good. That's helpful. But where did they go? To cash out their pimps? Or did they just drive around or sit in the parking lot until Kim wanted her out and she wouldn't get out? Was she trying to talk Kim into participating in a scam? Was she calling her BF and/or pimp?
The guys have a photo of someone helping the accuser into Kim's car at 12:41.
The neighbor said he heard someone yell at them "thank your grandpa for my nice cotton shirt!" as they drove away, so they probably started driving north on Buchanan around 12:41 or a couple of minutes thereafter.
The first 911 call is at around 12:55. Kim probably pulled over to the side of the road (after only driving a few minutes) to make the call. Since she was clearly trying to get rid of the accuser, she was probably also at this time trying to rouse the accuser (whom she did not know before this evening) to sober up enough to give her a telephone number to call her boyfriend or at least tell her where she lived so Kim could take her home. The accuser was probably passed out or uncooperative. Kim then probably headed west and onto Hillsborough Road(perhaps that's the direction where Kim lives) and when she saw the Kroger open pulled into the lot. She probably continued to try to rouse the accuser and convince her to get out of the car (maybe use the pay phone to call her boyfriend) for a few minutes before talking to the security guard. The security guard probably talked to Kim and looked over the situation for a few minutes before actually making a 911 call at 1:22.
So it is not clear to me that there is necessarily any unaccounted for time between leaving the house and arriving at Kroger, the activities seem to fit the time line.
