DULUTH (AP) - Crews have removed the wreckage of a fatal plane crash from Lake Superior.

St. Louis County Rescue Squad Captain Tom Crossmon says crews retrieved the wreckage and were returning it to shore Monday afternoon.

Divers would have to head nearly 140 feet underwater to retrieve the wreckage.

The sheriff's office has identified the plane's owner as 47-year-old Alexander Obersteg of Steinfeld, Germany.

Authorities recovered Obersteg's body two weeks ago and believe he is the sole victim of the crash. An autopsy ruled out the possibility of a medical emergency contributing to the crash, but the exact cause is still under investigation by the Federal Aviation Administration.
