This particular story is consistent with GBH and Ketamine.
Now, how did she come to believe she was raped? Well, Kim took her to the late night building guard for help. I presume she knew the guy. Let's assume he was of no help and advised Kim to take her to the Dope Crisis Center (as reported elsewhere on this same thread). So, she does that. And it would be there that someone might say, "Hey, this is a rape ~ look at these bruises ~ take her to the hospital to get tested", which Kim then did.
All of these cooborated events look quite rational in light of the lady having been doped with one of two different date rape drugs (as referenced above in my prior post).
I would hope the hospital did a blood test. One drug can be detected for 48 hours. The other for only 12 hours.
lol
Please go read up on this case. You're presuming things that aren't true.
You're making it up.
There are a lot of links on these threads which will lead to facts, rather then speculation on your part.
