LOS ANGELES, Apr. 20 – A maze of legal tangles may conflict with a judges announced resolve that the Sharon Tate murders trial begin June 15.

A clutter of courtroom complexities surrounding the six persons charged in the slayings has kept the hippie-style band from trial for four months.

“You need a scorecard to keep track of this case,” sighed one prosecutor who has watched lawyers and judges enter and exit during pretrial proceedings.

Judge Charles H. Older, 52, set the now trial the Friday and said there would be no more continuances.

“There’s a practical limit as to what the court has to put up with,” he said.

However, clan leader Charles Manson has indicated he will persist in courtroom outbursts, continue filing motions asking to represent himself and, if that is denied, may change lawyers again. Ronald Hughes, Manson’s third lawyer of record so far, says he thinks Manson may fire him.

Meanwhile, Manson’s five co-defendants — all members of his nomadic “family,” — have shunned the umbrella of a common defense and attorney. Although the prosecution wants to try them together, the six are taking separate courses.

Susan Atkins, 21, whose eyewitness account of last August’s bizarre slayings led to the arrests and indictments, wants to retract her story. Her attorney, Daye Shinn, filed a motion for suppression of her confession Friday.

Linda Kasabian, 21, a young mother who recently gave birth to a baby in prison, may replace Miss Atkins as key witness for the prosecution. She remains sequestered from other prisoners, and her attorney says she’ll probably be granted immunity for her testimony.

Leslie Van Houten, 20, has undergone psychiatric examination at her lawyer’s request, indicating a possible change of plea or an attempt to prove diminished capacity.

Patricia Krenwinkel, 22, after being denied a request to defend herself, has employed an attorney who quit his job as a deputy public defender to represent her. Paul Fitzgerald says he’ll appeal a denied motion to change the site of the trial.

Charles Watson, 24, named by Susan Atkins as leader of the killing expedition, remains in a Texas jail, appealing a court order that he be extradited to California. His hearing in the district court of appeals is set for Wednesday in Austin. Prosecutors say that if he arrives before the trial, he could file pretrial motions and challenges.

Manson succeeded Friday in removing from the case Superior Court Judge William B. Keene with whom he clashed during courtroom exchanges. Keene accepted a peremptory challenge, tardily filed, saying Manson probably was unable to understand that the law requires it to he filed earlier. No reason for removal is needed under a peremptory challenge.

The case now goes to Older’s court. Older has presided on the criminal bench since 1967 and is described as a “no-nonsense judge.”

Meanwhile, Manson and Miss Atkins face separate murder-conspiracy charges in the slaying of Malibu musician Gary Hinman. Both were indicted in that case last week.

Another Manson family member, Robert Beausoleil, 22, was convicted Saturday of first-degree murder in the Hinman slaying.
