Jack Leon Cooper, 70, went missing on August 23, 2001, after a boat capsized while fishing with friends at Salmon Creek Beach in Sonoma, California. He was described as 5 feet 7 inches, 165 pounds, with brown hair and brown eyes. His companions were rescued but Cooper disappeared and was never seen or heard from again.

Investigators believe he drowned in the incident; an obituary in the Press Democrat listed him as lost at sea on that date. Cooper was an avid fisherman and golfer, belonged to a Saturday morning men’s club at Oakmont, and was a U.S. Army veteran who served in Korea. He was survived by his wife, children, and a sister. The case is classified as lost/injured missing and is being handled by the California State Parks Police Department.

Did anyone in the Salmon Creek Beach area that day see or hear anything about the capsized boat or Cooper after the incident?
