Are you questioning that she went to Syracuse -- which even ESPN's chryon pointed out -- or that "alumnus" is incorrect? Just to be sure (the above was from Webster's) -- here's this from Wikipedia:
Williams competed in the Miss Syracuse (University) beauty pageant when a campus musical she was in was canceled in 1983. After winning the Miss Syracuse title, Williams won the
Miss New York crown in 1983, and went to compete for the Miss America title at the national pageant in
Atlantic City. Prior to the final night of competition, Williams won both preliminary competitions (talent and swimsuit) earlier in the week. Each day's preliminary competitions have winners announced. Therefore, there can be as many as six "prelim" winners: three each for talent and swimsuit. To win a "prelim" in both is a strong precursor to success in the finals. She was crowned
Miss America 1984 on September 17, 1983, becoming the first African-American to win the title.
[6] Williams' reign as Miss America was not without its challenges and controversies. For the first time in pageant history, a reigning Miss America was the target of death threats and hate mail.
