There's a couple of cases I remember seeing on Crimewatch when I was younger that I've not been able to find since to see whether they were ever solved.
Firstly, a old man who had been attacked in his home & stabbed in the neck/shoulder with an ice pick & dragged to the cupboard under the stairs where he laid for days before being found. He survived but refused to talk about it. I remember it suggesting that he perhaps knew the person who did it.
Secondly, a young girl on a night out who was attacked down an alleyway close to where lots of people were hanging around. CCTV caught the guy entering & leaving the alleyway but the strange thing about the case was the girl awoken to find she was wearing a Me To You nightie? So the guy had changed her clothing?
Does anyone else remember these cases? Or have any of their own?
