Lucy..

(Yes picture looks like a guy I know it was the best I can get) Lucy was the biggest singer in your country at the time she had the most amazing songs and basically the most popular,you were the biggest fan you would listen to her songs all the time You would always think she's so cool I wanna be like her but you never got to meet her until you went to her concert what you didn't know is that she was a killer she would lure people into the back and kill them without anybody noticing she had been doing this for a couple years and you were her next victim(You can be any age but it has to be a teen)
