Manson/Serial Killers/Wet specimens

I need to start reading books about my interests and not just articles.

Can anyone tell me about the best/most accurate biographies/autobiographies on the Manson trials?

Also serial killers.

Also I want to start learning more about collecting and preserving wet specimens of dead or fetal animals, so if anyone can give me some tips or forward me to some literature on the subject, it would be much appreciated.
