The awesome panel gathered for LS's video this evening seem to believe the body is buried. This is the reason:
"As an offer of proof, the People and law enforcement believe we are close to discovering the victim’s body. The People were hopeful that the search for, and the discovery of, the victim’s body would be concluded well before trial, but weather has complicated the efforts. Specifically, the area law enforcement has been focused on is in a remote and mountainous region nearby the Morphew residence. This area received a significant amount of snow over the winter months before a search could be completed. To date, the area has 5 feet of snow concealing the location where the People believe Ms. Morphew is located. As a result, the People cannot safely excavate this area and resolve this unanswered question."

To be clear, this suffices as a good faith reason to get their motion to dismiss over the hurdle. But that's all it need be: good faith. If it comes to nothing, and personally I lean that way, then mission accomplished as far as the DA is concerned regarding that.
