The reopening of the Patrick Santos cold case
from The Big Story · host Maria Kestane, Fil Martino, Steen Hartsen
It's taken Toronto Police more than 20 years to charge a suspect in the murder of Patrick Santos, a 21 year old Scarborough man that was found zip-tied and duck taped in his home in 2006. Investigative genetic genealogy was able to match the DNA sample taken from the crime scene to that of Pierre O'Connor, a Hamilton man who had no previous criminal record. Host Maria Kestane speaks to Fil Martino, co-host of Tracking a killer, to dig into the details of the 20 year-old cold case. Then she's joined by Steen Hartsen, a faculty member of the British Columbia Institute of Technology to learn more about genetic genealogy - including its ethical risks.
