'Kay. How about this:

Did She Jump Or Was She Pushed? None of the above.

First of all, a quick typo-spotting:

      "Yes. When I arrived home, I saw him across the street,
watching then wrap Akane's body. He had a very strange look on

          ^^^^
Now here's some spoiler space for anyone who doesn't want to see my
solution just yet:

Now then. What I think happened was: Ranma and Akane decided to run
away together, but they didn't want people to follow them. So they
asked Cologne to obtain for them some of the water from the
Akane-niquan created by Kima in vol. 38. This they used on Nabzy's pet
rabbit, which they killed, thereby faking Akane's death. Kuno-chan
overheard Ranma arranging for Nabs' help in this, and misunderstood.

Nice theory, except that Nabiki said that her bunny died several weeks
ago.  If had suddenly gone missing, she would have said so...

On the other hand, what if that's metaphorical as well as actual? 
Maybe, unable to buy a pregnancy test without dying of embarrasment (or
getting killed by the other fiancees), Akane performed the classic test
on Nab's pet, and she and Ranma worked this out when 'the rabbit died'. 
Hmmm... Maybe I'm thinking too much.
