FOREST, Miss. — The Mississippi man known as "Case 1," the first person to be diagnosed with autism, has died.
Donald G. Triplett was the subject of a book titled "In a Different Key," a PBS documentary film, BBC news magazine installment and countless medical journal articles.
But to employees at the Bank of Forest, in a small city about 40 miles (64 kilometers) east of Jackson, he was simply "Don," WLBT-TV reported.
