Authorities have continued efforts to recover the bodies of four people missing since a small plane plunged into Lake Michigan while flying a cancer patient to the Mayo Clinic.

Mason County Undersheriff Tom Trenner says recovery efforts resumed Tuesday morning, with boats in the water and crews searching beaches between Ludington and Manistee. They also were looking for signs of the plane.

Trenner said nothing new was found Monday.

After combing the area for 27 hours, authorities abandoned hope Saturday of finding alive the four missing since the crash Friday several miles off the west Michigan coast. The pilot was rescued.

The plane was flying to Minnesota from the central Michigan town of Alma.
