I wonder, is this denial partly to protect the girl? So she won't believe her Dad killed her mother? Also, KW's mother might have been shocked and shamed by the very public revelations of her online life.
But they seem to be unnecessarily harsh comments about KW (tho the media can take remarks out of context if the speaker isn't careful). If the comments are accurate, perhaps there was a bad relationship between KW and her mother, and JW and his family have exploited it. For eg, how would KW's mother know about her supposed previous acts of late-night drunkeness, unless informed of them by JW?
