RICHMOND, Va. (AP) _ The executive director of the hospital where two infants were switched at birth and where a woman was given the wrong corpse after her baby died has resigned.

Michael J. Halseth, executive director of the University of Virginia Medical Center since 1989, will become president and chief executive of Valley Health System, a group of hospitals, the university said Friday.

Hospital officials said the resignation was unrelated to the baby switch and corpse mixup that became public this summer.

In a statement, Halseth said the Valley Health opportunity was presented to him in June, a month before the baby switch came to light. The switch occurred in 1995.

Lawrence Van Hoose, vice president of Valley Health System, said an offer wasn't extended to Halseth until last week.
