4 - Murdered: Eva Blanco

In 1997, Spain, Eva Blanco asked for her curfew to be extended so
she could go out to a disco party. At 11:45pm, her and her friend
split up to walk home, and she was only 700m away. When she
didn’t make it home by 12:00am, her father and a couple of
friends go out and search for her. The next morning, her body is
found, and the 18-year-long search for a killer begins.
