Hollywood — Sheriff’s officers said there were few clues today to the killer of Marina Elizabeth Habe, pretty 17-year-old daughter of writer Hans Habe.

The girl’s body, stabbed at least half a dozen times, was found in a bushy ravine of the Hollywood hills three days after she had left home on a date.

investigators said she probably was slain some distance away and left near winding Mulholland Drive. “There is no evidence of forcible rape,” said an autopsy surgeon, Dr. Russell C. Henry

Henry said there were knife wounds on the front and back of the body and that the girl had been beaten on the head and body with a small blunt object.

After the autopsy Thursday, Sheriff’s Lt. Norman Hamilton said there were indications that more than one person was involved. He declined to give details.

Miss Habe was spending the Christmas holidays from the University of Hawaii where she was a freshman with her mother, actress Eloise Hardt. Their home in West Hollywood is a few miles from where the body was found.

The father, from whom Miss Hardt has been divorced for 10 years, flew Thursday from his home in Zurich, Switzerland. He declined to discuss the slaying with newsmen except to say at New York’s Kennedy airport: “You know more about it than I do.”

Habe, 57, a novelist wgo has written 18 books, said he last saw his daughter last summer.

Microscopic and toxicological tests were underway to determine more closely the time of death. Hamilton said it has determined only that Marina was killed sometime after 3 a.m. Monday. He said police had no suspects.

The murder could have been committed by one person, Hamilton said, although there were some indications that more than one person was involved.

He said Miss Hardt believes there might have been two men in the car that apparently carried off the girl from her driveway, although the mother saw only one man in the vehicle.
