Same here.
BTW the chaperones on our trip were spread out on the bus, not all in the front. We knew nothing could have happened, but still worried when the allegation was made. What and How did we miss it, if true?
One thing that you may have been wise to consider, was if he had been with the girl in close proximity to the bus trip.
If they had relations a day or two within the bus trip, he could have looked pretty bad if there was a DNA match or something.
I’m glad he was cleared.
Suffice it to say, there’s no way she was raped on the bus, if you folks were disbursed among the riders.
