A woman, while at the funeral of her own mother, met a guy whom she
did not know. She thought this guy was amazing. She believed him to be
her dream guy 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 is her motive for killing her sister?

The killer's sister had his phone number and wouldn't give it to her....
