Retired Highway of Tears investigator in awe of DNA science that traced suspected killer

Investigators knew to secure the scene for evidence when they found Colleen Rae MacMillen’s body on a logging road about 25 kilometres south of 100 Mile House about a month after she went missing in 1974. They bagged the 16-year-old’s clothes, which were found in the bushes nearby, and sent them to the forensics lab to test for fingerprints, hair and fibres.
