Well, at least some fat woman didn't roll over on him and smother him in the night.
Although there haven't been any recently, for a while there were numerous incidents of college kids drowning in the Mississippi in my old hometown of La Crosse, Wisc. Quite a few people suspected there was a serial killer on the loose targeting male college kids. The fact is these kids were found with no marks on their bodies suggesting there was no struggle with an assailant. The most likely conclusion: they got severely drunk, became disoriented, and wandered down to the river, which is only a block or two from many bars in La Crosse, and fell in. Once in the river, the swift current and the cold water most of the year would make it extremely difficult for a sober person to extricate themselves much less someone extremely inebriated.
In fact, several young males have been fished out of the river after falling in claiming to have no idea how they fell in. Others have been caught staggering towards the river and forcibly made to go in the other direction towards the UW-La Crosse campus. In virtually every incident of a student being stopped and made to turn around, the student insisted he was going in the right direction.
Easier to walk down hill when drunk?
But a bigger qustion remains: where were their buddies? I think all kids should be cautioned to stick with companions when out for a night on the town. Then, if you fall in the drink, somebody can raise an alarm.
When I was in college (back in the dark ages) we were prohibited from being out at night alone. Of course, we were women. But, even the guys in living groups were not out wandering around alone. Part of it was because there were few cars, so the students formed groups around the lucky guy who had a car. Still, we didn’t show up missing. We saw each other home and waited until our companion was inside before leaving. Of course this prevented couples from spending the night with each other, but that was prohibited in those days too. It was a good system.
