"Arnold's cellmate told the court that she had confessed to putting her daughter in the microwave and switching it on, because she was afraid that her boyfriend would leave her if he discovered that he was not the baby's father."

Its not a laughing matter but im pretty sure if he found out she'd just put her baby in a microwave he might have left her.
How could any sane person do that?
