Hi, I'm a student of police science. I am looking for information on a bizarre series of homicides from the 1970's.

The case involves the murders of young college girls. The victims would return to their apartments after classes and the killer would hide within their apartment.

He would only target girls wearing mini-skirts. He would first thing push them on their beds and place a pillow over their faces and smother them to death.

He would revive them and smother them three or four times before they actually died. After killing them he would remove his victims pantyhose. He would keep their pantyhose as a sick trophy.

He would not rape his victims. they were all found fully clothed with the exception of their missing pantyhose. His signature was always the taking of his victims pantyhose. Has anyone any information on this killer?
