CHICAGO, Oct. 8 (AP)--Dr. Alice Lindsay Wynekoop underwent a "psycho-detectometer" test today which its inventor said proved "without a doubt" she did not murder her son's pretty wife in 1933.
    Dr. Wynekoop, 77-year-old physician, was released from Dwight Reformatory last December after serving the minimum time of 13 years and 9 months on a 25-year sentence for murder. Rheta Gardener Wynekoop, her daughter-in-law, was slain on Nov. 21, 1933.
    Told that the test had showed she was innocent, the frail, white-haired woman burst into tears. Then she turned to Dr. Orlando Scott, inventor of the device and said:
    "I've only lived to prove my innocence. I can never thank you enough."
    The elderly woman steadfastly maintained her innocence at her arrest, during her trial and after her release from the reformatory.
    Dr. Scott said his instrument measures electrical impulses in the body and brain. Dr. Wynekoop could not take the conventional type of lie detector test, he added, because her blood pressure is too high.
    He said the meter showed she was "100% okay" and had "no knowledge of who killed the girl."
    However, Alexander Napoli, Assistant State's Attorney, said the State would take no official cognizance of the test. Lie detector tests, he said, are "inconclusive and not admissible as evidence in a trial."
    "Mrs. Wynekoop was given a fair and legal trial and was convicted," he said. "Her conviction was upheld by the Supreme Court and she served the time. There is nothing for us to do about it."
