To expound your point even further- all classes of people murder. All classes of people are accomplices. It doesn't matter if you are a male, female, upper or lower class, a maintenance worker or a doctor- people murder for love. People murder for money. People murder for hatred or to get rid of a "problem" in their life or relationships- such as a wife, child, etc.
It's amazing seeing folks thinking this nurse, because she is sssoooooooo intelligent, might not be involved, because she is also a Mommy, and oh no, she just wouldn't do that! Maybe she is not involved in harming Kelsey, maybe she has a reasonable explanation for disposing the phone (I doubt that very much, sorry), but to me, it's an insult to those who aren't as educated or have such a prestigious job (in some folks eyes here)- it's an insult to insinuate that a certain kind of person just wouldn't do that because what- they're above the rest because of higher education and job? That's what this sounds like to me, sorry. The shock and horror of an educated nurse and Mommy being involved in something evil has me scratching my head- have we not all been on here and other sites long enough to know that intelligence and job descriptions don't mean a damn thing when it comes to murder?
