Jerry Burns, 66, faces a first-degree murder charge in the case. Police say he fatally stabbed Martinko in her parents' car outside Westdale Mall in December 1979.
Then 18-year-old Michelle Martinko was a senior at Kennedy High School when she died.
The case remained unsolved for 39 years until police obtained DNA from a straw that Burns left at a Manchester restaurant. Investigators say DNA from the straw linked him to bloodstains at the murder scene.
Burns' attorneys argued the DNA evidence should be thrown out because police didn't use a warrant to get the straw. A judge later ruled it could be included.
The trial is expected to last two weeks in Scott County.
