Wisconsin Woman Records 'Shark' in Lake Michigan

Wisconsin resident Carlin Hastings said she was walking along Lake Michigan's McKinley Beach in Milwaukee when she spotted a large fish with a shark-like dorsal fin swimming in the water. 

Hastings took a video of the fish, and posted it to her Facebook page on Christmas, along with the caption "Its [sic] possible I might've seen a shark in Lake Michigan on Friday!"

Wisconsin Department of Natural Resources spokeswoman Cheryl Masterson could not definitively identify the fish, due to the video's poor quality, but speculated it could be a large sturgeon or chinook salmon.
