LOS ANGELES, Feb. 21 – A taciturn Patricia Krenwinkel Friday night was brought back from Mobile to face murder and conspiracy charges in the macabre murders of actress Sharon Tate and six others.

Miss Krenwinkel, 22, stepped off of Eastern Airlines flight 87 at Los Angeles International Airport at 8:38 p.m. and was quickly led past newsmen and photographers before the other passengers debarked from the big two-toned blue jet.

Los Angeles Police Detective Sgts. Olivia Conner and William Carey whisked the brown-haired, brown-eyed Miss Krenwinkel to a waiting unmarked police car. Lt. Paul LePage drove the 20 miles to police headquarters.

Then, she was booked into Sybil Brand Institute for Women, where she will remain until Tuesday at 11 a.m. when she will be arraigned before Superior Court Judge George M. Dell on seven counts of murder and one charge of conspiracy.

Ironically, as Miss Krenwinkel was being booked, the famed “Spahn Movie Ranch” — the place where she and other purported members of a nomadic band of hippies called home at the time of the Tate slayings — was the scene of a small fire. Firemen reported a barn on the sprawling ranch caught fire shortly before midnight but the blaze was quickly extinguished.

However, the blaze erupting on the night of Miss Krenwinkel’s arrival added one more note of mystery to the murder case which has had overtones of mysticism, sadism and ritualism. Authorities have twice scoured the ranch galleys and wells for bodies informants reported were buried there.

Los Angeles Attorney Ira K. Reiner, who has consulted with the alleged mastermind of the seven slayings, Charles M. Manson, held a hurried midnight meeting with Miss Krenwinkel.

Later, he told The News:

“I’m not her attorney of record but I anticipate representing her.”

Reiner would not elaborate on his conversation with Miss Krenwinkel but he apparently explained to her that there might be a question of conflict of interest if he represents her in that he is representing Leslie Van Houten, 20, Monrovia, Calif., one of the six defendants in the slayings. Miss Krenwinkel, wearing a brown and blue-checked dress, and black shoes, remained stone-faced as she stepped from the jet and moved to the waiting car. Later as she was taken to the identification section of the Police Department, she smiled briefly as a photographer snapped her picture.

Her arrival here marked the end of nearly two-month effort by Los Angeles authorities to return her. She was arrested Dec. 1 in Mobile and had resisted all efforts to extradite her until 10 days ago.

That was when she dismissed her Alabama attorney, M. A. Marsal, and wrote a note to Mobile County Dist. Atty. Carl Booth:

“I wish to sign extradition papers and return to Los Angeles immediately.”

After embraces by an aunt and a cousin, Miss Krenwinkel boarded the plane in Mobile Friday and headed for Los Angeles. She declined to comment when questioned by newsmen at Dallas, Texas, and Los Angeles.

Her return leaves only one defendant in the case still out of the state. He is Charles D. Watson, 24, who has been jailed in McKinney, Texas, since Dec. 1. The Texas Court of Appeals last week ruled he would have to stand trial in California but his attorneys promptly appealed to the Texas Supreme Court.

A trial date of March 30, has been set for Manson, 35, and three other defendants: Susan Atkins, 21 of San Jose, Calif., Linda Kasabian 20, of Concord, N. H., and Miss Van Houten.
