LOS ANGELES, Mar. 24 – Attorneys for Linda Kasabian revealed the strategy to be used in seeking immunity for their client when they said Monday they will ask for a trial date separate from the other Tate-LaBianca murder suspects.

The others now here, including hippie leader Charles M. Manson, are scheduled for trial before Superior Judge William B. Keene April 20.

Charles D. Watson still is in Texas fighting extradition. But a development there Monday may reduce the delay in his return to California.

Gary B. Fleischman and Ronald Goldman, who are defending Mrs. Kasabian, indicated that they will request that her trial date be set later than the others.

Prosecutors Aaron H. Stovitz and Vincent T. Bugliosi, who reportedly now are relying on the woman to be their key witness, presumably will not oppose the motion for a separate trial date.

Mrs. Kasabian appeared briefly Monday before Superior Judge Malcolm M. Lucas, who is hearing pretrial motions in the case, so her attorneys could withdraw their request for a transfer of the trial to another county.

“We no longer are unhappy at having the case heard in Los Angeles County,” Fleischman explained later.

He and Goldman also had Mrs. Kasabian sign a waiver so that her appearance will not be required at any other pretrial hearings in the future.

That and their disclosure that they will seek a separate trial date both indicate their desire to keep her as secure as possible until she actually is needed to testify.

A proposed agreement whereby Mrs. Kasabian would testify against the other Tate-LaBianca defendants in return for immunity became public last week.

However, it is understood that Stovitz and Bugliosi consented only on the condition that she truthfully relate in court what she knows about the murders last August.

Mrs. Kasabian’s testimony is potentially damaging to the defense because she reportedly accompanied the killers on both murderous forays — to the Tate Benedict Canyon estate and to the LaBianca home in the Los Feliz area — although she was not present when the slayings actually occurred.

In McKinney, Tex., Monday, Dist. Judge David Brown sustained a state motion to rush the extradition of Watson.
