Her memorial stone is not a grave, and we don't actually have a corpse. I wrote a fic where Raven killed Summer as an act of mercy as her mind was about to be taken over, and Salem was about to possess her and turn her against her loved ones. Another lovely creepy possibility is that Summer is Salem, that Salem is a malevolent spirit in need of a body, and Summer's one would do with a few slight modifications. Or maybe she died in an act of "Save yourselves! I'll hold them back!"

We know very little about Raven and her motivations. We know she's pretty powerful (Ozpin/Cinder grade, perhaps), but not all-powerful. She may genuinely have more important things to think about than her daughter.
