A former colleague of mine worked part time as a county coroner -- he wasn't a Forensic Pathologist, in fact he wasn't even even a Pathologist. I don't know how the Connecticut State Medical Examiner's system is set up. The doctor could be completely accurate about the description, but the only fact I'd be very confident of is that the children might or might not have been killed with a rifle. (Medical Examiners generally try to avoid TV cameras because anything they say can and will come back in court.)
You've got to be kidding me.
