Authorities say a humpback whale found dead this week off a Danish island has been identified as the animal released two weeks ago in a spectacular and controversial rescue effort after repeatedly becoming stranded off Germany’s Baltic Sea coast. The dead whale was washed up on Thursday just off the small island of Anholt in the Kattegat, the broad strait between Denmark and Sweden that connects the Baltic Sea to the North Sea. The site is south of the location where the whale that gained the nicknames “Timmy” and “Hope” was released on May 2 after being transported toward the North Sea in a special barge.
