“Any evidence of a date rape drug won’t be there after 12 hours.”
Could very well be, I have no idea. But you can’t just make it up because it’s possible.
Based on the current prevalence of the date rape drug, I’d say it’s not just possible something was slipped in her drunk, it’s quite likely.
No one leaves a drink around in a bar these days. The kids hold onto it, keep it close, and watch it constantly. At a house party people are more relaxed but it’s still not safe. Given that the boys apparently did this once before and the girl was totally out of it then, I’d say she was probably given a drug.
The picture I saw posted of the girl being dragged around like a rag doll by two boys (yep, she was out like a fried light bulb) makes it seem not just possible, but likely. To get catatonic like that takes one heck of a lot of alcohol, or some kind of knock out drug.
We can't 100% know, but that picture is fairly convincing.
