They are not a strange family. They are a very normal family who worked hard and made some money the good old American way- they earned it. Tragedy can strike any of us at any time. And ,yes, I do know the family. No one in that family is capable of murder.
I knew a family once and said the same exact thing.."No one in the family could murder someone"....HOWEVER, the husband DID kill the wife's ex-husband and she helped him dispose of the body in a canal! Nicer people you couldn't meet!!
