LOS ANGELES, Sept. 22 – A prospective witness in the Charles Manson murder trial yesterday claimed that a prosecutor called her obscene names and told her he would see that she got the death penalty.

The claims were contained in an affidavit presented to the trial judge Charles Older by Manson’s attorney, Irving Kanarek. It was signed by Sandra Good 26, a member of the Manson cult.

Miss Good has been subpoenaed by the prosecution to testify later in the trial of Manson, 35, and three of his female followers accused in the murders last August of Sharon Tate and six others.

The affidavit accompanied a petition by Kanarek asking Judge Older to set a hearing on possible contempt action against Dep. Dist. Atty. Vincent Bugliosi.

The charges were discussed by Judge Older and attorneys in a closed-door session in chambers. The judge took the affidavit under advisement and gave no indication when he would rule on it.

Bugliosi denied the charges.

Miss Good said in the affidavit that Bugliosi approached her last Friday outside the Hall of Justice where the trial is taking place.

The young woman has been wandering around the hall for several days.

In the affidavit, Miss Good claimed that Bugliosi called her names, including “vicious murderer.”

According to the affidavit, Bugliosi told her, “I’m going to get you good — I’m going to have you behind bars if it’s the last thing I do and see that you get the death penalty.”

Bugliosi gave the following statement to newsmen:

“With respect to the limited portions of the affidavit that are true, if all of the facts of my confrontation with Miss Good were known, it would be abundantly clear that my response to Miss Good was exceedingly mild under the circumstances.

“A much harsher response on my part would have been totally justified,” the prosecutor said.

Bugliosi asserted, “I would like nothing better and I would welcome the opportunity to relate all the circumstances surrounding the confrontation.”

“However, the courts’ order on publicity precludes me from doing so,” the deputy district attorney explained.

He referred to an earlier order which prohibits principals from making extra-judicial statements concerning the case.

In her affidavit, Miss Good said Bugliosi’s language during Friday’s confrontation was “Willful, malicious and designed to obstruct the orderly process of the justice proceedings and trial” in connection with the case.”

Another witness was Miss Ruby Pearl who has been stable manager of the Spahn Ranch near Chatsworth for the past 20 years.

The ranch, on Santa Susana Pass Road, was stronghold of Manson’s “family” at the time of the murders last year.

Miss Pearl, who will continue testifying today, said Manson, another man and several women, including co-defendant Susan Atkins, showed up at the ranch in the summer of 1968.

They were riding in a big black bus, she said, and stayed on after ranch owner George C. Spahn told them they could have free room and board in exchange for work around the ranch.

Miss Pearl said she never Manson do any work, but several times heard him give his followers orders.

The orders, she said, were carried out.

Miss Pearl also testified that although the “family” began as a small group, it later grew to 20 or 30 persons, including co-defendants Patricia Krenwinkel, 22 years old as is Miss Atkins; 20-year-old Leslie Van Houten, and 24-year old Charles (Tex) Watson.

Watson is being tried separately since he battled extradition from Texas for nine months before being returned to Los Angeles earlier this month.

A firearms expert testified that shell casings found at the Spahn Ranch matched those from test firing of a gun which the prosecution claims was used to kill three victims at the Sharon Tate home.

The testimony came from Los Angeles Police Dept. Sgt William J. Lee. The prosecution claims the weapon used at the Tate house was a .22 caliber, nine-shot revolver.

A former motorcycle gang leader, Danny DeCarlo, has testified that the gun looks like a “Buntline Special” which Manson had as his favorite gun.

Lee, a ballistics specialist, said of the 45 .22-caliber shell casings he found in a gully at Spahn Ranch, 15 were fired from the gun used at the Tate home.

Lee said his opinion was based on compression marks left on the casings by the firing pin of the gun.

The witness testified he recovered the casings from the ranch on Nov. 19, 1969, and last April 15.

“It is my opinion that four of the casings I recovered Nov. 19 were fired from this revolver.” Lee said, handling the gun allegedly used at the Tate estate.

“Eleven casings I recovered on April 15 were fired from this .22-caliber revolver,” he said.

DeCarlo, on the witness stand for the third day, was questioned about defense contentions that Manson prohibited guns at the Spahn Ranch.

He said that when he first moved to the ranch, Manson did say he wanted no guns there. However, DeCarlo said the cult leader never specifically ordered him to dispose of a gun collection which DeCarlo had brought to the ranch.

Manson, DeCarlo commented, “liked knives better than guns.”

Bugliosi also questioned DeCarlo about Manson’s strange mystical beliefs, particularly about Manson’s theories of a white vs. black civil war.

He said Manson pressed admiration blacks for “having guts to fight police.”

The prosecution tends that Manson ordered the mass slayings and then tried to make it appear that blacks were responsible — this to touch off racial warfare which would leave the “family” in power.
