Sick sea lion rescued on Alameda's Crown Beach dies

ALAMEDA, Calif. (KGO) -- A sick sea lion named Wilbur that was rescued from Crown Beach in Alameda on Tuesday has died.

The 300-pound, 7-foot-long mammal was rescued by a team of volunteers early Tuesday morning. They say he was lethargic at the time and barely moved when a net was put over him.

Wilbur passed away at the Marine Mammal Center in Sausalito later in afternoon.

He had been out of the ocean for more than 24 hours.

A necropsy will be performed tomorrow.
