DAVENPORT, Iowa (The Gazette) — Jurors have convicted a man of murder in the killing of an Iowa high school student more than 40 years ago. It took jurors about three hours to convict 66-year-old Jerry Burns of first-degree murder in the December 1979, stabbing death of 18-year-old Michelle Martinko. Her body was found the next day inside her family’s car at a Cedar Rapids shopping mall.

Burns didn’t testify, and his defense called only one witness. The trial was moved to Scott County District Court in Davenport because of pretrial publicity in Cedar Rapids. In Iowa, first-degree murder carries a mandatory term of life in prison.
