Guam – An autopsy has been completed on the Navy's Ryan Bennett, who died last Saturday after snorkeling at Haputo Beach. The military flew a forensic pathologist out to Guam to conduct the autopsy. But until the report is completed and the death certificate is signed by medical examiner Dr. Aurelio Espinola, Bennett's body cannot be returned to his family in Pennsylvania.

The cause of death has not been released but a CBS affiliate's interviews with Bennett's family and a friend who was swimming with the sailor last week suggest that he may have gone into shock after being stung by a jellyfish.

Bennett was a Navy diver aboard the USS Frank Cable.
