The mother-in-law of Mrs. Rheta Gardner Wynekoop, Chicago beauty, questioned in the latter's mysterious slaying, was classified yesterday by a Washington physician as a philanthropist and a woman of high intelligence.
    Dr. George L. Knapp, of the 3500 block of McKinley street northwest, whose family employed her late husband, Dr. F. E. Wynekoop, as physician, said yesterday in referring to Mrs. Frank E. Wynekoop, the mother-in-law:
    "I have never known a kinder, or more intelligent woman than Mrs. Wynekoop. Her brains were far above the average. Moreover, she was a real philanthropist and raised two children besides her own. She did much work in Chicago among the poorer people."
    "It's quite impossible that she had anything to do with the death of her daughter-in-law unless she was insane, and she certainly wasn't when I saw her in Chicago several years ago."
    Dr. Knapp said he had known Mrs. Wynekoop for 13 years, during which her husband had been his family physician.
    Referring to a letter which Mrs. Wynekoop wrote and never mailed, saying she had "seen" Dr. Knapp and her husband in conversation in the office next to the operating room where the young woman was found slain, Dr. Knapp said:
    Mrs. Wynekoop never displayed any signs of mysticism or spiritualism beliefs during the time I knew her."
