Sharon Tate’s sister Debra Tate is like most Americans when it comes to the controversial marriage of notorious murderer Charles Manson.

She doesn’t understand why he would even be allowed to marry.

According to Fox News, Tate has spent years fighting the system to make sure Manson spends the rest of his life in prison.

So, of course she finds this latest development to be quite “ludicrous.”  Now, she’s speaking out about her displeasure of the entire debacle.

“It’s always something with him,” she said. Apparently Manson’s bride-to-be, 26-year-old Afton Elaine Burton, has absolutely no idea who he really is.

Several media outlets have reported that Burton believes he’s an environmental enthusiast focused on “saving the environment.” However, Tate definitely isn’t buying it. “I wonder how long it will take for her to figure out this is just a con,” Tate said.

“It makes me wonder what is missing in her life that she would want to marry an 80-year-old man. Is she a victim? Is she mentally deranged?”

But, there’s no doubt she’s committed to him. Shocking details about their relationship definitely prove she’s committed to making things work regardless of his incarceration.

Burton reportedly moved to Corcoran, California at the age of 17 just to be closer to Corcoran State Prison.

Although Burton claims to be “in love” with the 80-year-old convicted murderer, many speculate Manson’s motives for marriage are simply for personal gain.

She has openly professed her love for him and intends to fight for his exoneration. If she marries him, she’ll reportedly have access to his personal information, which would normally be denied to people considered nonrelatives.

However, Tate is fighting to make sure he’s never released. She’s also working to prevent the spread of his following on the Internet.

“I don’t want any more heinous actions by another family like his because of something I didn’t do,” Tate said.
