A beachcomber found the head of a man killed three weeks ago in a great white shark attack in Northern California.

Sports fishing advocate Randall Fry was killed Aug. 15 while diving for abalone. His friend told authorities Fry disappeared after what he called a "big fish" appeared between them.

Last Friday, an unidentified person walking on Ten Mile Beach (search) north of Fort Bragg (search) found Fry's head. It was identified Tuesday by Mendocino County (search) authorities as belonging to Fry. The rest of the body was recovered the day after the attack.

Fry, 50, was the 11th person to die in a shark attack on the West Coast since 1952.

Experts speculate the shark may have mistaken him for a seal or sea lion.
