FRONTERA, Calif., Sept. 3 — Mass murderess Susan Atkins, once a member of Charles Manson’s “family” of drug-driven killers, married a self-described Texas millionaire Wednesday in a private prison ceremony described as highly religious.

Miss Atkins, 33, once sentenced to death for her role in the ritualistic 1969 Tate-LaBianca murders, exchanged vows with Donald Lee (Fla$h) Laisure, 52, of Greenville, Texas, shortly before 3 p.m.

“It was a highly religious wedding,” attorney Michael Gunn, a friend of Laisure’s, told reporters after the ceremony.

“Susan wore a deep teal blue French satin gown. She also wore a crucifix and crosses on her ears. The groom wore a coral-colored leisure suit and a cowboy hat.”

Laisure disclosed earlier he sketched the wedding dress and paid $6,000 to have it made by a designer in New Jersey.

Robert Pope, Miss Atkin’s prison counselor, gave her away, and another prison inmate served as maid of honor. The wedding was witnessed by about 25 guests, including several other inmates and prison officials.

Gunn said the bride and groom took communion during the wedding, which also included a tape recording of a song sung by Miss Atkins. He said Laisure provided flowers for the ceremony and a wedding cake for a reception afterwards.

It was disclosed after the ceremony that prison officials had given the newlyweds, who originally expected to have just one hour together, a little extra time to celebrate the nuptials.

Gunn said the groom was allowed “through the beneficence of prison officials” to stay with Miss Atkins at the prison visiting area until 8:45 p.m., the end of normal visiting hours.

Late in the afternoon they were seen sitting alone and talking at an outside picnic table. The bride, still wearing her wedding dress and baby breath flowers in her hair, waved to onlookers, but the prison guards did not allow any other communication.

Laisure arrived at the prison with two friends a few minutes before the wedding. His gold-colored Cadillac was embellished on the right fender with black-and-gold stick-on letters spelling out his bride’s name.

The groom, wearing dark glasses, waved a wad of money and a Texas flag as he walked into the facility in a rural area 35 miles east of Los Angeles.

Laisure, who claims he has been married and divorced more than 30 times, said his marriage to Miss Atkins was “something that has been brought on by God, ordained by God. I love her very much and I never did love another woman.”

He said only employees or inmates at the prison were permitted to attend the wedding. His wife invited about 16 guests, including a prison captain and lieutenant.

Laisure said he is building a $12 million solar house near the prison and will live there until his wife is released. He claims to have spent $6.4 million in efforts to free his wife and said he is prepared to spend another $100 million.

Miss Atkins, who said she became a born-again Christian seven years ago, lost her last bid for parole on grounds she had a criminal history, showed “callous disregard” for the murder victims and displayed no remorse at her trial.

Laisure, known as Fla$h in his hometown because he likes to carry a big roll of cash, said he inherited wealth but would not reveal where his family made their money.

“I can only tell you that I have more money than I could spend in the next 500 years and that I’m no crook,” he once said.

Laisure said he met his bride 16 years ago in Southern California. Miss Atkins, who was 18 at the time, told Laisure she was instantly attracted to him and the couple has been “close” ever since, he said.

Two years later, she met Manson and joined his cult of drugs and sex, becoming one of his most loyal followers. She was known as Sadie Mae Glutz in the Manson Family.

She confessed to the Aug. 9, 1969, murders of actress Sharon Tate and four others in the home Miss Tate shared with her husband, film director Roman Polanski, and the killing the following night of Leno and Rosemary LaBianca.

Miss Atkins, along with Leslie Van Houten and Patricia Krenwinkle, were sentenced to die in the gas chamber for the two-night massacre, but the state Supreme Court later overturned California’s old capital punishment law.
