The world has come to know Charles Manson as a monster with a scraggly beard and crazed eyes.
But at one time, he was once a normal-looking teenager years before he put a swastika on his forehead. In a picture taken when he was 13 years old, Manson looks like the boy next door.
Author Jeff Guinn gathered the early, never-before-seen photos of Manson for his new book, Manson: The Life and Times of Charles Manson.
Guinn told INSIDE EDITION, "The expression on his face never changes. The look in his eyes. The sly little grin. It's the expression of somebody who's one step ahead of the other person, and plans to take advantage of that."
The book shows the future mass murderer at age five. It also shows Manson on his first day of elementary school in McMechen, West Virginia.
"The first known instance we have of him physically attacking someone, He was seven years old and he tries to murder his cousin JoAnn with a razor sharp sickle," said Guinn.
By age 19, Manson had grown into a deeply disturbed young man with a bad reputation. But somehow at age 20, he managed to convince a pretty teenager named Rosalie Willis to become his wife. That's right, Manson, was married.
Guinn explained, "He marries one of the prettiest high school girls in town. Rosalie worked in a grocery store. Pretty, pretty girl. And no one in town could understand, what's she want to do with that kid?"
INSIDE EDITION's Paul Boyd asked, "Manson was already a known trouble-maker. How did he convince this girl to marry him?"
"Charles Manson could be the most charming guy you'd ever want to meet," said Guinn.
The marriage lasted just two years. Guinn says Manson used his charm to manipulate his followers to commit the brutal 1969 Helter Skelter killing spree which took the life of actress Sharon Tate and six others.
Guinn says, Manson's not crazy, just evil. An evil spoiled brat.
"I've talked to people who grew up with him. Their term for Charlie is not abused. Their word is spoiled," said Guinn.
