A 20-foot Minke whale died after colliding with a motor boat at the Jersey Shore, officials said. The force of the collision sent a boat passenger into the water.

A whale was killed after it was struck by a motorboat off the New Jersey shore, with the forceful collision sending one passenger overboard. Video footage shared online of the sudden collision showed the motorboat rocking back and forth as the 20-foot-long minke whale swam away in Barnegat Bay on Saturday afternoon.

On Monday morning officials will tow the whale from Barnegat Bay to a New Jersey state park where they will perform a necropsy to determine the cause of death.
