Charles Manson's fiancee used him for his ... corpse?

Convicted murderer Charles Manson's bride-to-be was reportedly using him for his body.

The 80-year-old convicted murderer and 27-year-old Afton Elizabeth Burton (a.k.a Star) received a marriage license in November and had 90 days to wed. The ceremony was postponed when Manson became ill and had to go to a medical facility.

Now, journalist Daniel Simone, the author of a new book about the killer, told the New York Post that Manson's fiance had a plan to put Manson's corpse on display.

Along with friend Craig Hammond, Burton reportedly wanted to display Manson's body in a glass crypt, much like Lenin's tomb in Russia. The goal was apparently for the attraction to rake in a ton of money.

That creepy plan aside, Simone says that Manson, 80, never actually wanted to marry her anyway.

FOX 2 News reports that: "Simone says Burton and Hammond initially wanted Manson to sign papers granting them ownership of his body, but the killer balked at the notion, so the two conceived the idea for Burton to marry Manson. The law in California, where Manson is incarcerated, grants spousal ownership of remains."

"He's finally realized that he's been played for a fool ... Manson never consented to the wedding in the first place and never will," Simone told The New York Post. "He feels he will never die," Simone said. "Therefore, he feels it's a stupid idea to begin with," the Post reported.

Burton has not yet commented on her foiled plan. Burton's mother, Melissa Burton, told FOX 2 News that the Post article is not true. "She is my daughter no matter what is going on in her life. You would love her unconditionally too if she were your child."

Manson and Burton's wedding was in trouble ever since it was reported last week that their marriage license was set to expire.

On Monday the 2nd, The Associated Press reported that, "Afton Elaine Burton and the 80-year-old Manson obtained a 90-day marriage license late last year. It expires Thursday, making this past weekend the couple's final opportunity to hold a wedding inside a visiting room at California State Prison, Corcoran. If the wedding is to happen, the couple must register for a new Kings County marriage license."
