A question for anyone interested

Read this question, come up with an answer and then scroll down to the bottom . This is not a trick question. It is as it reads. I want to see if anyone out there can come up with the right answer.





A woman, while at the funeral of her own mother, met a man who she did not know.

She thought he was 'amazing'. She believed him to be her dream partner so much,

that she fell in love with him right there, but never asked for his number and

could not find him.



A few days later she killed her sister.





Question:



What was her motive for killing her sister?



Give this some thought before you answer,leave a comment with your answer and I will post the answer later.....if there is actually anybody who reads this blog :-)
