Notorious mass murderer Charles Manson, 80, and his 26-year-old devotee Afton Elaine Burton are yet to marry, even though their marriage licence is about to expire. The couple, whose 90-day marriage license was drafted in November, will expire on Thursday.

"A Manson wedding did not take place," Terry Thornton, a spokeswoman with the California Department of Corrections and Rehabilitation revealed to LA Times. Generally, wedding of inmates take place on Sundays during the visiting hours and therefore, their final window for a wedding with the existing marriage license has already gone by.

Burton, who goes by the name 'Star', left her home In Illinois and has spent the last nine years living near the Central California prison, claiming to be in love with the mass murderer. She also maintains websites advocating Manson's innocence.

It is not understood why the couple has not gone ahead with their nuptials, but James McGrath, a New York City photo agency editor claiming to be in touch with Star, said that they intend on obtaining another 90-day license and go ahead with the marriage.

Although Manson is not allowed 'conjugal visits' or overnight family visits, he is allowed to have "contact visits", meaning the wedding ceremony would not require a glass door separating the couple.

Manson has been in prison since 1971 for his role in the murder of pregnant actress Sharon Tate and six others in Los Angeles County in 1969. Although he was initially sentenced to death, it was changed to life in prison when California abolished death penalty for a time in the 1970s.

Manson's next parole hearing is scheduled for 2027, when he will be 92 years old.
