LOS ANGELES, Aug. 3 – A woman with whom Linda Kasabian, chief prosecution witness in the Tate-LaBianca murder trial, lived after the killings testified today that Mrs. Kasabian was a “liar” and a constant user of narcotics.

Mrs. June Emmer was taken to Los Angeles Superior Court from her home in Miami Beach, Fla., to give a deposition of what she knew about Mrs. Kasabian.

The two-hour questioning interrupted the testimony of Mrs. Kasabian, who had been on the stand for more than a week.

“When she was carrying her first baby, Tanya, she took LSD but told me not to believe what I read in the papers about it,” Mrs. Emmer said. “She said, ‘Look at that baby. There’s nothing wrong with it.’ ”

Mrs. Emmer, with whom Linda lived in October and November, 1969, said the girl told her she had “a ball in Los Angeles and certainly enjoyed it.”

Mrs. Kasabian also admitted being in several $250,000 homes in Los Angeles but refused to give a reason, Mrs. Emmer said. Mrs. Kasabian’s reputation for truth was challenged by Mrs. Emmer but following lengthy legal haggling the statement that Mrs. Kasabian was a liar by reputation was stricken.

“She said she was living in the hills of California off the fat of the land,” Mrs. Emmer testified after questioning by defense attorney Irving Kanarek.

“When I asked her why she had left her husband she said he had fallen in love with another woman but she didn’t care because the woman was one of her girl friends.”

Mrs. Emmer’s deposition probably will be read to the jury during the defense testimony at a later date.

Mrs. Kasabian resumed the stand later today and was expected to testify further as to her part in the killings of actress Sharon Tate and six others.

On trial with hippie cult leader Charles Manson are three of his girl followers, Susan Denise Atkins, Patricia Krenwinkel and Leslie Van Houten.
