I found most of the main information from Wikipedia.
I'm too lazy to write all the names of the source-websites. :D
Also too lazy to write what fex. movies have the "killers" done.
Other sources Google.
I take every suggestion!
Sorry for poor writing. I'm from Finland.
There are also people have been involved/convicted on killing and are later proven innocent/found not guilty and or released. Sorry for "misleading".
