There was a paperback book out on the subject. It said that the wife's crazy sister had already attacked the kid once and was not allowed to be alone with the baby. She was left alone and the baby died.

A lot of the crime scene information was trashed. What was not messed up was suspicious. It is not clear they really found the baby's body. They found A baby's body. There are many strange things involved in the whole affair.

Thanks for providing the additional info.

I did a quick search and found this "review" of the 1994 "sister" theory at a site called CrimeLibrary:

"While the writing is quite good, and the accounting of the facts of the crime reasonably complete, Behn has no evidence for his theory, and admits to its speculative character."

Honestly, I think it pretty mean of the author to malign poor Elisabeth Morrow in this way without a shred of evidence, for the sake of selling a juicy story...she was sickly and died young of a heart ailment. A sad enough life without tacking on lurid speculation.

I suspect there will always be wondering about the unanswered questions surrounding the tragedy, but unless and until someone can come up with some concrete facts to go along with this particular theory, this one goes in the "fantasy" category, IMHO.
