The Deaths

Hi I'm Rown, Rown Rosy I'm 38 and I've been working as an detective for years and I'm one of the top detectives in our small city welp back to what has been happening.
One mouth there were twenty dead female in a row all the same age and all with black hair, what could this mean I'm a simple homicide detective.
And this this is my case right here! it all started in the 1940's
And my job is to stop this sick kid and keep the city safe.
Why, why would someone want to do this the murders are all the same but there in different places and different positions.

First murder Ella Rosy she was 25 and walking home from work when she went missing she had long beautiful black hair.
She was found by the mall in the forest right across from it. She was positioned with here eyes closed and he mouth was wide open with her tongue cut out, she had no clothes and her hand had a book.
It was the worst murder I have ever seen! This case will be huge pain in my a**.
Soon after the first murder there were about three people going missing a week some body's were never found but after five year there were about 50 dead bodies counted.
Then they all stoped I stayed with the department for three years after those deaths then retired.
