LOS ANGELES, Apr. 11 – Mary Brunner, testifying under “complete immunity” in the retrial of Robert K. Beausoleil, gave jurors Friday an eyewitness account of a weekend of terror which finally resulted in the death of musician Gary Hinman.

Beausoleil, 22, who lived during the summer of 1969 with Charles M. Manson’s hippie “family,” is accused of stabbing Hinman to death in the musician’s Topanga Canyon home last July. His first trial last November ended in a hung jury.

Miss Brunner, 26, a member of Manson’s family for about a year, said she, Beausoleil and Susan Atkins, another family member, went to Hinman’s home Friday, July 25, to “ask Gary for some money — $3,000 or $30,000 — I don’t remember.”

During the next 48 hours, Miss Brunner testified, Hinman — kept captive in his house — was clubbed with a pistol, slashed across the face with a sword, stabbed in the chest and then smothered with a pillow.

After she and the two others left Hinman’s home on Sunday evening, they stopped at a nearby restaurant, disposed of bloody rags, and “went in for a cup of coffee and had a piece of cake,” Miss Brunner told the seven-woman, five-man jury In Los Angeles Superior Judge William B. Keene’s courtroom.

Miss Brunner, a soft-spoken, plain-looking woman with close-cropped blonde hair, was promised by Dep. Dist. Atty. Burton Katz before she testified that she would receive “complete immunity at the conclusion of the proceedings.”

Another witness at the trial testified that he overheard a conversation in which Manson and Beausoleil said Hinman was “a political pig and he should die.”

The witness, Danny DeCarlo, member of a motorcycle gang, testified Monday and said Beausoleil also told him that Manson ordered Hinman’s death.

Manson, accused of masterminding the seven Tate-LaBianca murders, has not been charged in the Hinman case.

Miss Atkins is charged along with Beausoleil in the musician’s death. Her trial is scheduled to begin April 23. She also is one of six co-defendants in the Tate and LaBianca slayings.

Miss Brunner, a 1966 graduate of the University of Wisconsin, told the jury that when she, Beausoleil and Miss Atkins arrived at Hinman’s home shortly before midnight on the 25th she was armed with a pistol and Beausoleil was carrying a sheathed knife, attached to his belt.

Beausoleil asked Hinman for money, drew the pistol from Miss Brunner’s purse, and said “we were not kidding,” Miss Brunner testified.

“They had a fight,” Miss Brunner said. “Gary was pushing at Bobby (Beausoleil) and Bobby was hitting Gary with the gun.”

Miss Brunner said shortly after the fight, Beausoleil made a telephone call, reportedly to Manson at the Spahn Movie Ranch in Chatsworth, which at the time was home for the family.

After the call there was another fight for the gun, during which a bullet discharged into a kitchen cupboard, Miss Brunner said. Then Manson and another member of the family, Bruce Davis, arrived at Hinman’s home.

There was more fighting, at which time Manson reportedly severed Hinman’s left ear with a sword, the jury was told.

The young woman said she later tried to sew up Hinman’s ear with a needle and dental floss.

A short time after the attack with the sword, Manson and Davis returned to the ranch, Miss Brunner said.

The next few hours were relatively quiet, Miss Brunner said, and she and the others took turns to make sure “Gary would stay where he was.”

“He had a cut on his face but other than that he was pretty good,” Miss Brunner said when questioned by Katz about Hinman’s condition.

Hinman’s death came late Sunday afternoon, after Beausoleil made a second call, reportedly to the Spahn ranch, Miss Brunner said.

It was at this time that Manson reportedly gave Beausoleil the order to kill Hinman.

She and Miss Atkins were in the kitchen and Beausoleil was in the living room and, then, “We both heard this noise in the living room and Gary had been stabbed,” Miss Brunner told the jury.

“Then we started cleaning up the house,” she added.

After wiping up the blood and fingerprints, the three prepared to leave. Than “Gary started breathing real loud,” Miss Brunner said, adding: “I guess people do that when they die.”

Beausoleil reportedly went back into the living room and smothered Hinman’s gasps with a pillow.

Before they left for the last time, Beausoleil smeared in blood on the wall above Hinman’s body the words “Political Piggy” and the likeness of a “cat’s paw” to make it look as if Black Panthers had murdered the musician, Miss Brunner said.

The word “pig” also was left at the homes of actress Sharon Tate and Leno LaBianca after those slayings.

Throughout Miss Brunner’s testimony, the baby-faced Beausoleil sat quietly next to his attorney, Dep. Public Defender Leon Salter, showing little emotion.

The trial recessed for the weekend before Salter had a chance to cross-examine Miss Brunner, who is jailed at Sybil Brand Institute on a charge of violating probation. She was arrested Thursday.

Judge Keene earlier Friday denied a plea from Patricia Krenwinkel, another of the co-defendants in the Tate-LaBianca murders, for state-financed services including an investigator, a clinical psychologist, experts in handwriting analysis and blood typing and a photocopying service.

In dismissing the motion by Miss Krenwinkel’s attorney, Paul J. Fitzgerald, Keene said affidavits concerning Miss Krenwinkel’s financial resources were not completed and that Fitzgerald had not exhausted the possibility of volunteer help. Fitzgerald said his client is without funds.
