On the subject of unsolved crimes, I remember years ago reading about what was called the Tunbridge Wells Bedsit Murders, just horrific- two young girls attacked and killed in their homes. It really bothered me as I lived in places like this - dodgy rentals with not great security and dark doorsteps.
Years passed without hearing about it and I thought it would never be solved, one day my eyes popped out of my head when I read one line in a newspaper about how an arrest had been made. It was David Fuller, later found to have attacked hundreds of women in a hospital mortuary and filmed it. He had killed Wendy and Caroline before the job at the morgue gave him easy access to women’s bodies.
So, I feel there is always hope. Cold cases are solved even decades later, but how families exist without ever knowing what happened is so tragic.
