As someone who works in law enforcement I tend to believe certain aspects as to what the media reports. So let’s look at what I believe:
1. The child was left in the car.
2. Someone broke the windshield after seeing the child in distress.
3. At least one media outlet reported the mother shopping with two other children. If that is true then I question why they did not say anything about the baby.
4. If you consider this a “conviction in my own mind” then there is nothing else I could write that will convince you otherwise.
