How does this even happen? Then again, how do parents leave their kids in a hot car with the windows closed in the middle of the summer? 

While the uncle of a toddler, who was found walking on Second Avenue in Troy Wednesday evening, is saying this is just an accident., my question is? How does an 18-month-old little boy find his way out of the house in only a shirt and diaper without an adult noticing? Seriously!?
