LOS ANGELES, Aug. 19 — Linda Kasabian, the Manson “family” member who turned state’s witness, testified during cross-examination that she did not try to prevent the murders of the Tate victims or go for help while they were being killed.

Miss Kasabian 21, was making an appearance for the second day on Tuesday in the trial of Charles (Tex) Watson, the remaining defendant in the Tate-LaBianca mass murders.

Defense attorney Sam Bubrick, under cross-examination, asked Miss Kasabian if she had expected to see anyone murdered at the time she reportedly saw Watson shoot the first of five victims in the driveway of the Tate home.

Miss Kasabian testified she had expected to rob the group at the home not watch them get murdered.

Bubrick asked Miss Kasabian what she had said to Watson after she said him commit the murder.

“I said nothing,” she answered.

The star prosecution witness earlier had described Watson as a young man “very much in control”‘ of himself during the two nights of murder in August of 1969.

The testimony elicited by the prosecution apparently was aimed at countering defense claims that Watson 25, was mentally affected by heavy drug use and was merely a “robot” directed by cult leader Charles Manson.

Miss Kasabian, who claims she went along on the two missions of murder said Watson was composed and calm both nights.

Following the five slayings at the home of actress Sharon Tate, she said, the “family” members stopped to use an outdoor hose to wash off the blood.

At the point, she said, Watson calmly told the others he had to “get a drink of water.”

Much of Miss Kasabian’s testimony Tuesday was a repeat of the story she told in the earlier trial of Manson and three female followers.

Watson is being tried separately because of delays in extraditing him from Texas last year.

Miss Kasabian is regarded as the star prosecution witness in the case. She herself was granted immunity from prosecution after she turned state’s witness.

Manson, Susan Atkins, Leslie Van Houten and Patricia Krenwinkel previously were convicted and sentenced to death for their parts in the murders of actress Sharon Tate and six other persons.

Five of the murders occurred at Miss Tate s Benedict Canyon home. The other two — those of Mr. and Mrs. Leno LaBianca — occurred the following night at the couple’s home in the Los Feliz area.
