This week we welcome back forensics expert, and author of a book on his experiences with the Swiss Air disaster, Tom Juby. Tom discusses the DNA evidence that was presented at the Mass Casualty Commission, and theorizes on what the presence of two unknown DNA samples might mean. Paul and Adam discuss the missing children case out of Pictou County, where police have announced that they have received over 5000 videos from the area where they were reported missing. Is this the new norm for investigations? What might it mean that the person speaking for the RCMP is a behavioral analyst?
