A St. Paul woman who waited months before getting treatment for a burn on her disabled adult son's foot, leading to an infection so severe his leg had to be amputated, was sentenced Monday to two years of probation.

Christine Ruth Nelson, 61, pleaded guilty in April to a gross-misdemeanor count of neglect of a vulnerable adult, which could be reduced to a misdemeanor if she successfully completes probation. Ramsey County District Judge J. Thomas Mott also lifted a no-contact order so Nelson may be able to see her son, who has a new legal guardian.
