Charles Manson was born in Cincinnati, Ohio to 16-year-old Kathleen Maddox. Kathleen had run away from home at the age of 15 and spent the next few decades drinking too much, with periods of time spent in jail.
Since his mother couldn't take care of him, Charles spent his youth at the homes of various relatives and often at special reform schools and boys homes. By age nine, Charles Manson had already started stealing and soon added burglary and stealing cars to his repertoire.

He believed that when he got out of prison, he could be a famous musician.
Through an acquaintance, Manson met and hung out with Dennis Wilson of the Beach Boys. The Beach Boys did record one of Manson's songs, which appeared as "Never Learn Not to Love" on the B-side of their 20/20 album.
