Could new national DNA database provide a break in one of Alberta’s most gruesome cold cases?

Septic Tank Sam lies in an unmarked grave in an Edmonton cemetery, his identity no less a mystery than when his tortured body was pulled from a rural septic tank on a spring day in 1977.
But 40 years after Sam met his grisly end, cold case investigators hope a new national DNA database will give fresh leads on who he was — and who killed him.
Set to launch in 2018, the RCMP’s national children and missing persons unidentified remains database will allow investigators to compare DNA from unidentified human remains to DNA from living relatives who offer a sample in hopes of finding answers about a missing loved one.
