Minnesota Supreme Court’s seven judges came to Edison High School in northeast Minneapolis Monday to hear arguments in the case of True Thao, who was convicted in a 2013 gang-related murder outside a St. Paul bar.

The biannual school visits aim to teach Minnesota students about the court system. This was the last such visit for Justice Alan Page, who will retire this year at age 70. He spoke with the students after the hearing, encouraging them to use their talents and succeed. Michael Walker, director of Edison’s Office of Black Male Student Achievement, awarded a plaque to Page in recognition of his work in public schools and through the Page Education Foundation.

Walker said Page, a former Minnesota Viking who has served on the state’s Supreme Court for 22 years, “is an example for all of us.”
