I find this case interesting as my grandma has a slight relation to it :))
My grandma had long dark hair most of the female victims had dark hair so females were changing their hair color in fright. My grandma liked her hair color so she refused to change it, resulting in her being avoided by everyone for fear of their safety. I had also been told by her that she was good friends with one of the female victims. She had been injured badly as she was left fully paralyzed for the rest of her life.(I never got her name) I have always been fascinated at this case and with unsolved mysteries in general so this is cool to me. my grandma was a teen at this time. She was never targeted but she lived very close to the crime scenes as we are from new york but she was in the area of the crimes.
(I dont know if this is all factual i probably got stuff wrong, this is from what i remember she told me. she passed in 2012 so nothing i can do)
