The former University of Maryland professor found dead near Lake Artemesia on April 1 died of a heart attack complicated by drowning, a spokesman for the state medical examiner said Wednesday.

Stan Fromovitz was reported missing on March 13. A university student discovered his body along the Indian Creek Trail during this university’s sixth annual Good Neighbor Day. The death was ruled accidental, said Bruce Goldfarb, spokesman for the Chief Medical Examiner’s office in Baltimore.

A Holocaust survivor originally from Poland, Fromovitz was a statistics and quantitative methods professor in this university’s business school from 1971 to 2001. The business school will name its building’s third-floor library after Fromovitz, and will put a plaque there in his honor.

Fromovitz is survived by his two first cousins and two second cousins, all of whom live in Ontario, Canada.
