MARINETTE, Wis. (AP) — An 84-year-old man was convicted Tuesday of murder in the 1976 shootings of a couple camping in a northeast Wisconsin park. A jury in Marinette County returned verdicts soon after beginning deliberations in the trial of Raymand Vannieuwenhoven. Their judgment wrapped up a case that grew cold over more than four decades until DNA technology led to an arrest. Vannieuwenhoven was charged with two counts of first-degree murder in the deaths of 25-year-old David Schuldes and 24-year-old Ellen Matheys at McClintock Park. Sentencing is scheduled for Aug. 26.
