Charles Manson, who died in prison in November, knew he had an estate; and he made plans for it to go to his pen pal, according to TMZ in "Charles Manson Will Surfaces Pen Pal Gets Everything."
While Manson was in prison, he developed a friendship with someone who the press is not identifying by name for privacy reasons.
The man and Manson became pen pals. They even talked on the phone and the man visited Manson in prison.
This relationship prompted Manson to write a will in 2002 leaving the man everything Manson owns and specifically disinherits all of Manson's known family members.
There might actually be some value in Manson's estate, since collectors may want some of his personal items and Manson wrote a few songs that he copyrighted.
