LOS ANGELES, Aug. 20 – Linda Kasabian completed her testimony in the Tate-LaBianca murder trial Wednesday, then said of cultist Charles Manson and three of his women followers:

“I would like to see them fall down on their knees and beg for forgiveness.”

“Do you think they are capable of that,” asked a newsman.

“No,” she said. “I think they don’t realize what they have done.”

Mrs. Kasabian, 21-year-old mother of two, made her remarks at a press conference after completing 18 grueling days as the state’s key witness.

In that time, the petite, pigtailed blonde told of two nights of murder when she saw two men slain at the home of actress Sharon Tate and accompanied Manson “family” members in a random search for victims the next evening.

But, she was not talking about that at the press conference. Her attorneys, Gary B. Fleishman and Ronald Goldman, limited questions to her thoughts and plans.

Speaking quietly and serenely, in a small girl’s voice, she said she planned to continue life as a hippie but not in a commune with others.

“I’d like to go into the wilderness with my children. Get down to nature and get hold of myself and closer to God,” she said.

“Linda, do you feel you deserve to be free today?” a newsman asked.

“Well,” she replied, “I don’t think the legal law of immunity is right but I feel I have told the truth and that I probably helped a lot of people.”

Under Fleischman and Goldman’s direction, Mrs. Kasabian won immunity in exchange for her testimony about the murders of Sharon Tate and six others. The charges were dropped and she is free.

One of the things she doesn’t want to do is remain in California.

“l’ve done my thing here a long time ago,” she said. “Way before this.”

Presumably, she will return East as quickly as possible to pick up her children, Tanya, 2, and Angel, 5 months, and seek her “wilderness” under another name.

She may return later in the trial as a defense witness because she is under subpoena and on 48-hour call.

Meanwhile, at the trial, the prosecution began the process of corroborating her testimony.

The young woman had testified that the night she was at the Tate residence last summer she heard screams, ran toward the house and saw a bleeding Voityck Frykowski coming out the front door.

The first witness called by the prosecution in the afternoon session Wednesday was Timothy Ireland, a graduate student and employe of the Westlake School for Girls, near the Tate residence.

Ireland testified that in the early morning hours of Aug. 9, 1969, he was helping supervise 35 children at a “sleep-out” at the school when he heard a man screaming for 10 to 15 seconds:

“Oh God, no! Oh God, no! Don’t! Please don’t!”

Ireland said he woke another man at the sleep-out, then went in his car searching for the source of the screaming. He found nothing, returned, and reported the incident to Beverly Hills police next day.

Manson’s attorney, Irving A. Kanarek, asked on cross-examination whether Ireland had written down the words he had heard.

“No sir,” he replied. “You don’t forget things like that.”

Ireland placed the time at about 12:45 a.m. on Aug. 9.

Mrs. Kasahian had testified on direct examination that after leaving the Tate house, the killers stopped to wash their hands with a hose in the yard of a home nearby.

The second witness was Rudolf Weber, a slender, white-haired retired chief steward of the Brentwood Country Club.

It was about 1 a.m. on Aug. 9, according to Weber, when he was awakened by the sound of running water outside his home at 9870 Portola Drive in Beverly Hills.

Rushing outside in his pajamas, flashlight in hand, Weber said he discovered three young women and a man standing in front of his house.

“Just what the hell do you think you’re doing?” Weber said he asked them.

“Hi,” he quoted the man as saying, “We are just getting a drink of water.”

Weber said he asked about a car parked in the street nearby, followed the four persons to it and flashed his light on the license number.

Later, he said, he wrote down the number — GYY435, then threw the paper away. He said he could not identify the persons he saw.

The first witness today is expected to be John Swarz, owner of a white Ford. Authorities claim it was used by Manson family members on two murderous forays from the Spahn movie ranch in Chatsworth.

The first night, they say, Mrs. Kasahian, co-defendants Susan Atkins and Patricia Krenwinkel, and Charles (Tex) Watson, a former family member still fighting extradition in Texas, drove it to the Tate residence.

The next night, a carload of people, including Manson and co-defendant Leslie Van Houten, were taken in the car to the Los Feliz district home of Leno and Rosemary LaBianca, authorities claim.

Mrs. Kasabian’s testimony, which began with an emotional account of mass murder, came to a stumbling halt Wednesday with objections from both prosecution and defense attorneys to questions by Kanarek.

Superior Judge Charles H. Older repeatedly denied Kanarek’s requests for a conference at the bench and admonished the attorney to get on with his questioning.
