LOS ANGELES, Jan. 22 — A Manson family member who testified for the state at the Tate-LaBianca murder trial failed to answer a subpoena today, and a bench warrant, without bail, was issued for him in open court by Judge Charles H. Older.

Thomas J. Walleman, 27, a former optical technician who looked after horses at Spahn’s Ranch, the family’s former headquarters, failed to appear in the trial room in answer to a subpoena from the state.

If Charles Manson is convicted of first degree murder, the prosecutor wants Walleman to testify at a penalty trial.

Walleman testified at the trial that after Manson received a midnight telephone call at the ranch Walleman accompanied Manson to an apartment in Hollywood. He said they took with them the long-barrelled .22-caliber revolver the state says was one of the murder weapons later used at the Tate house.

He was not allowed to give any more details, but it was reported that on that night a black musician was shot in the stomach.

The goateed musician, Bernard Crowe, 28, also was subpoenaed by the state as a possible witness for the penalty trial, if there is one, and came to the courtroom today.

Deputy District Attorney Stephen Kay, an assistant prosecutor at the Tate-LaBianca trial, asked the judge to order Crowe to appear at 9 a.m. Wednesday.

This could indicate that the prosecutors do not expect a verdict today or tomorrow from the jurors, who got the case a week ago today. If they expected a verdict, it was reasoned, they would have asked the witness to return on Monday.

Crowe told reporters he suffered a gunshot wound in the stomach on Aug. 1, 1969, and that the bullet is still lodged near his spine.

While the jury deliberated in the Hall of Justice, two other Manson family members appeared in two other trial rooms.

Brenda McCann, 19, pleaded innocent to charges of possessing drugs and attempting to bring drugs into the jail on a visit to Manson. She remained free on $2,500 bail, with a jury trial set for March 17.

Dennis Rice, 31, pleaded innocent to a charge of attempting to kill a state witness in the Tate-LaBianca trial with an LSD-spiked hamburger. He asked to be allowed to act as his own attorney. Argument on a motion to dismiss the indictment for lack of evidence was set for Feb. 4.
