No, I'm not a medical examiner. Are you? I can only go by what the poster said about DS hiring investigators and believing her son was suffocated. I have no reason to disbelieve her. The autopsy report does note that the child's death was attributed to lack of oxygen for a significant period of time. To me, that is an indication smothering was a possibility.
Please enlighten all of us as to the "lot of ways" an ME can determine with certainty the reason for death was "smothering" in someone who lives another week after they've suffered the lack of oxygen, followed by a fall into a chandelier suffering blunt force trauma. Links would be helpful. Thanks.

Usually a smothering victim has petechial hemorrhages (sp).
