Charles Tex Watson, imprisoned for his role in the Manson family Tate-LaBianca killings of 1969, was denied his latest request for release on parole on Wednesday, prison officials said.

The Texas-born Watson, who has been described as a former right hand man of criminal mastermind Charles Manson, has become a born-again Christian during his time in prison.

He was convicted in 1971 of seven counts of murder and one count of conspiracy to commit murder.
