Convicted mass murderer Charles Manson plans to marry a 26-year-old woman named Afton Elaine Burton, who runs several websites promoting his release and has spent the last nine years trying to help exonerate him.

Manson, who was found guilty of orchestrating the killings of actress Sharon Tate and four others with the help of two followers on Aug. 9, 1969, is not eligible for parole until 2027 and has spent most of his life in prison, The Associated Press reports.

There is no set date for the marriage, but a wedding coordinator has been assigned by the prison in order to handle the nuptials. The May-December couple has until early February to get hitched before they must reapply.

California Department of Corrections spokeswoman Terry Thornton confirmed to the AP that the marriage license had been transmitted to the prison. Thornton explained that the California prison designates an employee to be a marriage coordinator in order to processes paperwork for an inmate's request to be wed, and typically the Department of Corrections approves of such weddings, but, she pointed out, Manson is a unique case.

Burton, who goes by the name “Star,” claimed that the wedding might have happened sooner if not for "some situations" at the prison that had to do with Manson threatening the staff and refusing to provide a urine sample.

The prison holds marriages on the first Saturday of each month. Manson and his fiancée will be allowed to invite an officiate from outside of the prison to perform the ceremony as well as up to 10 guests who are not inmates.

Outside of an obvious devotion to the man who woefully misunderstood the lyrics to "Helter Skelter," the soon-to-be bride hopes that this marriage will allow her access to information related to the Manson case that is not available to non-relatives.

"There's certain things next of kin can do," she told the AP without elaborating.
