CHICAGO, Feb. 28. (Exclusive)--Walker Wynekoop, eldest son of Dr. Alice Lindsay Wynekoop, went to the witness stand at his mother's murder trial today to help save her from imprisonment or execution. The mother wept not for herself, but for him.
    The woman accused of the premeditated killing of Rheta Wynekoop, wife of her other son Earle, shed her first public tears in the case at a recess. Walker had spent an hour on the stand telling Judge Harry B. Miller and a jury of the indignities he asserted the police subjected her to before she signed the "confession" of an accidental killing, which she has since repudiated.
    Following Walker's testimony, court was adjourned to permit the defendant to rest for her great ordeal. Some time tomorrow Attorney W. W. Smith said, Dr. Alice will take the stand in defense of her reputation, her liberty, and perhaps her life.
    Except for Walker's story, the burden of today's testimony was merely that she had always shown affection for Rheta and was so fixed, financially, that she had no dire need for the $12,000 insurance she had placed on Rheta a month before the murder.
