In disgrace!
They failed to prove both homocide and that she did it. The autopsy was botched. They never established that she died abnormally. Failing that, it was pure speculation.
I personally believe she killed her. However, certain proofs have to be met and the entire case hinged on emotion and speculation and absolutely no evidence. Every point the prosecutor brought out was refuted completely by the defense. They claimed 85 searches for cholorform now they determined that it was maybe once. Little things like that will destroy a prosecution.
