Triathlete victim's autopsy confirm the culprit's specie!
A shark expert says an autopsy has confirmed it was a great white that killed a 66-year-old swimmer in the waters off San Diego County last week.
An investigator from the Medical Examiner's Office says two shark's tooth fragments were recovered from David Martin's body.
Los Angeles-area shark expert Ralph Collier assisted with the autopsy. He says the fragments indicate the shark was a great white 15 to 16 feet long.
Martin was bitten Friday morning while training for a triathlon. He quickly died from blood loss.
About 17 miles of coastline were closed after the attack.
Authorities reopened the beaches Monday without incident.
