The casket probably wasn't empty though because when Scott tells the others in the car he says that the Calaveras "switched bodies" when they found out Kate was turning so there was probably another random body buried in Kate's grave. I would guess the omega started digging up Kate's grave to eat the body in it but was scared away when Derek came and helped Isaac out of the hole.
