If you know the answer to this because of your profession please do not spoil the fun.

An attractive young woman suffers the unfortunate death of her mother.
While attending her mothers funeral she notices a very attractive man attending the service. From the sorrow she saw in the mans eyes she gathered he must have known her mother well even though she had no clue who he was.
Throughout the rest of the service she could think of nothing but him and how deeply she was drawn to him. For her it was love at first sight.
After placing a rose on her mothers grave she looked around only to find the man was gone.
After leaving the service she goes to her mothers house. Her sister is already there.
She pulls a knife out of the butchers block and uses it to kill her sister..............
