LOS ANGELES, Nov. 6 — Ruth Ann Morehouse, a former Manson girl, was freed by a judge who blamed her father for abandoning her to the weird gang when she was only 14.

Miss Morehouse, now 23, appeared Tuesday for sentencing for her role in the “LSD hamburger caper,” a bizarre plot by some of Charles Manson’s followers to prevent a witness from testifying against him in 1970 for the Sharon Tate murders.

They fed an LSD-laced hamburger to the witness in the Honolulu airport, hoping to unbalance her mind. The witness was hospitalized, but recovered.

Miss Morehouse, nicknamed “Ouish” in the family, pleaded no contest to the charge then, but disappeared while awaiting sentencing. When another Manson follower, Lynette “Squeaky” Fromme, was arrested in Sacramento two months ago for pointing a loaded pistol at President Ford, investigators found records giving Miss Morehouse’s whereabouts in the same city.

Superior Court Judge David Fitts Tuesday sentenced Miss Morehouse to 101 days, the time she had already spent in jail on the charge. He credited the time against her sentence, freeing her immediately.

He said he believed her statement that she broken all ties with the Manson family years ago, and thinks she “never had a chance” in her youth.

“This young lady was thrown willy-nilly into the Manson cult by her father at the age of 14,” the judge said, blaming her father for abandoning her.

Her lawyer told the judge that she did not appear for sentencing five years ago because she was nine months pregnant and “the (Manson) family told her she would have to shave her head and that she had to have her baby in jail, and she wanted none of that.”

Miss Morehouse had plastic surgery to remove the “X” she carved in her forehead, like other members of the group, to show solidarity with Manson. She said she had no contact with Miss Fromme or Sandra Good in Sacramento and was “scared to death” of reprisals because she left the gang.
