MADISON, S.D. — A court affidavit says a grudge spanning more than a half-century may have led a 73-year-old man to fatally shoot his long-ago classmate at his South Dakota home.

Carl V. Ericsson, of Watertown, was denied bond Thursday during his first court appearance on a first-degree murder charge. The former high school sports star is accused of shooting 72-year-old retired Madison High School teacher and track coach Norman Johnson after he answered the door at his house Tuesday evening in Madison.

An autopsy says Johnson died of two gunshot wounds to the face.

The judge denied a request to have Ericsson's bond set at $100,000, saying he was a potential flight or suicide risk. Ericsson faces a Feb. 16 preliminary hearing, at which he's expected to enter a plea.
