POWAY, Calif. (AP) — The man accused of opening fire inside a Southern California synagogue earned good grades in high school and swam on the varsity swim team. John T. Earnest also made the dean’s list both semesters last year as a nursing student at California State University, San Marcos. His embrace of white supremacy and anti-Semitism has dumbfounded people who thought they knew him. In high school, he basked in the applause of classmates for his piano solos at talent shows.
