How was Andrews described?

From the text:

Two years earlier Lowell Lee Andrews, an enormous, weak-eyed boy of eighteen who wore horn-rimmed glasses and weighed almost three hundred pounds, had been a sophomore at the University of Kansas, an honor student majoring in biology. Though he was a solitary creature, withdrawn and seldom communicative, his acquaintances, both at the university and in his home town of Wolcott, Kansas, regarded him as exceptionally gentle and "sweet-natured" (later one Kansas paper printed an article about him entitled: "The Nicest Boy in Wolcott").
