EXCLUSIVE: Did Charles Manson Have A Son?

INSIDE EDITION speaks exclusively to Matthew Roberts, who believes he could be the long-lost son of notorious murderer Charles Manson.

When Matthew Roberts looks in the mirror, he sees Charles Manson, because he could be the madman's secret son.

Roberts thinks he might be the long lost son of the notorious killer who ordered the murders of actress Sharon Tate and seven others in 1969.

INSIDE EDITION's Jim Moret said to Roberts, "When you look at the two of you, side-by-side, you definatly see similarities."

Roberts said, "It is hard to imagine we are not related."

When you look at Manson and Roberts side-by-side, their noses are similar and they both have that wild-eyed look.

Roberts told Moret, "I look at the pictures and oh my God, I look like this guy's twin."

So how did Roberts, a musician and DJ, come to believe he is Manson's son?

It happened when Roberts, who was given up for adoption, searched for his birth mother. She told him he was conceived when she had sex with Manson during a drug-fueled orgy in San Francisco.
           
INSIDE EDITION's Jim Moret asked, "Does this idea that Charles Manson is your father haunt you?"

Roberts replied, "Not as much as not knowing, because the last thing I want to do is think this guy is my father if he is not."
    
Roberts showed Moret his birth certificate. He was born in March, 1968. The name of the father was left blank. He contacted Manson and the two exchanged letters.

Roberts read an excerpt from one of the letters, "It's not that I didn't care. It was free love and you paid the price."

Manson is serving a life sentence at California's tough Corcoran State Prison. He refused to leave his cell to participate in a parole hearing last month.
    
Sharon Tate's sister, Debra, was there to see Manson denied parole again. He won't be eligible for another 15 years, then he will be 92-years-old, if he is still alive.

But time is running out for Matthew Roberts, unless Manson gives him a DNA sample so that the truth may be known, once and for all.
