I remember seeing this on UM. I believe the case was in CA. A mom and her son went missing and she was due to have a baby most anytime. Can anyone remember this case as well as the city she went missing from?

I did a little searching. It's Cecilia Newball I am thinking of. I wonder what would be the chance that the bones found in the planter in San Francisco would be her and her son. Lot of distance between LA and SF, but the idea popped in my head while reading an article about the bones.
