Preliminary autopsy results on two New Brunswick boys who were killed after an African rock python escaped its enclosure in Campbellton, N.B., show they died from asphyxiation, RCMP say. The pathologist completed the autopsies on Noah and Connor Barthe on Tuesday. "At least right now we have a cause of death. Even though we still need some reports from the pathologist to be forwarded, that's going to help the investigation to move forward," RCMP Sgt. Alain Tremblay told CBC News. Tremblay said in a statement that police are aware the case has "touched the hearts of people across the world"...
