“I don’t think this was an accident either.”
What makes you think it was on purpose? I suppose it is possible that some diabolical person could do something like this on purpose and then claim it was an accident, but if they were going to go to all that trouble it seems that they would come up with a better scheme, one not likely to get them in trouble or make them look like a horrible person. She had taken her kid to daycare the day before, but for some reason forgot to do it the day this happened. I think it is highly unlikely she did this on purpose. She just screwed up, really bad, and her screw up resulted in some horrible consequences.
