[Suzanne W]

The riddle is this: Do You Think Like A Psychopathic Killer?

Take My 1 Question Quiz Below:

An old lady dies of natural causes and is survived by two daughters.At the funeral, the oldest notices a man that takes her breath away, but she was never able to speak with him.
She asks everyone there if they know who he is – no one knows.
Some weeks later she kills her sister.
WHY?

Please help my OCD mind and tell me what I am missing...thanks

so that she can see the man again at her sister's funeral

[LurayGirl]

she blames her sister for their mother's death

[Danitza T]

Since the man took her breath away she wanted to see him again so she thought that if she killed her sister maybe he'll show up at her dead sisters funeral so she could see him again.
