Defendant, Nola Jean Weaver, a high school physical education teacher, was convicted by a jury of the Lake County circuit court of the murder of her husband, Larry Weaver. (Ill. Rev. Stat. 1975, ch. 38, par. 9-1(a).) She was sentenced to serve 40 to 60 years in prison. On appeal, the conviction was reversed and the cause remanded for a new trial. (90 Ill. App.3d 299.) We granted the People's petition for leave to appeal and now affirm the appellate court's judgment.
