OSHKOSH, Wis. (AP) – Winnebago County authorities say the body of a skydiver has been found in an Oshkosh-area lake.  A dive team began searching for the skydiving instructor after wind pushed him off course and into Lake Butte des Morts on Tuesday. The instructor was making a tandem 10,000-foot jump with a student.  Officials say the student swam to shore for help about 12:30 p.m. and was not injured.  The sheriff’s department says the instructor’s body was found shortly before 5:30 p.m. His name has not been released pending notification of relatives.
