So you put it in your kid's backpack and later the police will see that you spent your day in an elementary school. Does not seem like a very good alibi. The same is true for your neighbor, they will see that you spent your day in the parking lot of your neighbor's workplace, pretty suspicious.
So put in your wife’s purse and say you spent the day with your wife (maybe spousal privelege would be useful there)
Or hide it in a bar or at your workplace for a day
