A book by Ronald Markman and Dominick Bosco-
Published in August 1991, the author tested Leslie Van Houten for the original trial, and testified in her second and third. He also claims to have thought up the idea to change her charge to Robbery Homicide so a diminished capacity defense couldn't be used.
"As a forensic scientist, Dr Markman is often alone in a room with someone who
has killed - sometimes without provocation or apparent motivation. After lengthy
interviews and evaluations, his findings determine the degree of a murderer's
responsibility at the time of the crime and thus influence his sentence in
court. This is Markman's analysis of some of his toughest cases, including two
of Charles Manson's followers, Marvin Gaye's shooting by his father, the
infamous "Vampire of Sacramento" and Norma Jean Armistead, who wanted a baby so
much that she was willing to kill for it. The book should appeal to everyone who
has a morbid fascination about murder and wants to know more about the people
who have killed."
It's not the full chapter, but it's worth a read looking at things from a legal psychiatric perspective. Here is the link:
