We know, thanks to Jeff, that Monty put Summer in the grave in the Red Trailer at the last minute because Jeff asked if it was her mom and Monty thought the idea sounded cool.

What we don't know is if MMK ever planned for Ruby's mother to have any significance or presence in the story. According to what we mention on her page, Monty didn't really say that she was in the grave, only that it would be "cool" if it was her mom. It just seems weird for Qrow and Yang to say "she never came back" if they actually had her body buried in a grave nearby. One way to rationalize all that is if she deliberately let people think she was dead and left behind a bloody cloak amidst a bunch of Grimm. They find it, assume there isn't a body because she got eated, and thus those are treated as her only "remains" left. Alternatively, she may have severed a limb to make it extra convincing.
