ROCHELLE —Two nurses and a pilot were killed when the REACT medical helicopter they were flying in crashed at about 8:30 p.m. Monday in a field near Rochelle, the Northwest Herald is reporting.

The helicopter was flying from Rockford Memorial Hospital to Mendota to pick up a patient, the story said. Those killed include the pilot Andy Olesen, 65, and flight nurses Karen Hollis, 48, and Jim Dillow, 40, the Herald reports.
