The Mother of the kid has a screw loose. Leaves the 6-year old in the back seat of an unlocked car with the engine running, at 2am in the morning while she goes grocery shopping. And when the Cops come, fails to mention when she's giving information to the police about her car, that her kid is in the back seat of the car, and only mentions that important fucking piece of information to the police at a later time.
This Mother of the Year will very get filthy rich from people donating to online crowdfunding sites to pay for "funeral expenses" and then she'll just choose the cheapest cremation option and spend the rest of the donated money on new wigs, a new car, new shoes, new phone, vacation etc.
