I think someone else saw the garbage bag in the fridge besides MM. I'm thinking the lifelong friend whom RB confessed too could have seen something in the fridge at some point. Maybe he didn't necessarily open the refrigerator, but RB opened. HOWEVER, I have no doubt there would have been an odor emanating from the refrigerator. I guess she could have turned the refrigerator setting down as low as it would go and maybe partially froze the body, I still think there would have been an odor if they kept Bella's body in the fridge a month. I'm still thinking someone could have come into the apartment during those 3 to 4 weeks and say "I just went into Rachelle Bond's apartment today and it smells like a dead body has been in there."
It doesn't look good that MM was allowed to spank Bella. RB should have never allowed MM to lay one hand on the child. It does make it look like she was looking for a man to step to help her control and punish Bella.
I don't see how RB couldn't have known Bella had been found when she borrowed the wifi password from the neighbor. I think Bella's face was on everyone's home page at some point. I think she was following the story on the computer and television. Computer searches will be interesting for them as she was already calling herself an accessory after the fact. They probably went on another huge heroin binge after Baby Bella's body was discovered at Deer Island. It will all come out in the wash.
