Uhh, the list of items seized from the house includes a makeup kit with ID. Could be Kim had no address for the other woman and didn't know where to take her.
uUhh--since she made the first 911 call herself to complain about the racial epithets, why couldn't she make the next one herself? Why did she need the security guard's help and claim she picked the girl up on the road? Kim is a liar, sorry.
