MARINETTE COUNTY, Wis. — Charges have now been filed against Raymand L. Vannieuwenhoven in Marinette County, according to online court records.
Vannieuwenhoven faces two charges of First Degree Murder and one charge of First Degree Sexual Assault.
The Marinette County Sheriff's Office announced last week they arrested Vannieuwenhoven for the 1976 cold case double murder of 25-year-old David Schuldes and his girlfriend, 24-year-old Ellen Matheys. Authorities say a DNA match led them to that arrest.
According to previous reports , Sheriff Jerry Sauve said the couple traveled to McClintock Park from Green Bay. On July 9, 1976, they were camping and out for a nature walk when Schuldes was shot and killed. His body was found in the park. Matheys' body was found the next day. She had been sexually assaulted and murdered.
The criminal complaint says both victims were shot with a .30 caliber firearm.
According to the criminal complaint, authorities were able to construct a profile of a suspect through DNA technology, using semen recovered from Matheys' shorts. In 2018, the criminal complaint says a lab working with law enforcement used a genealogist to narrow down a suspect pool to a specific family of six.
The complaint says authorities did surveillance on a couple of different male family members, using DNA taken from their garbage or from a cup of coffee. Authorities eventually approached Raymand Vannieuwenhoven, asking him to do a survey about policing and then seal the survey envelope by licking it. According to statements in the criminal complaint, the saliva taken from that envelope was a DNA match to the semen in Matheys' shorts.
The complaint says law enforcement executed a search warrant at Vannieuwenhoven's home last week. The criminal complaint says deputies found a 30-30 lever action rifle in a cabinet in his garage. They also located four 30-30 shell casings in a tin can on a shelf above the washer and dryer.
Online court records show Vannieuwenhoven is due to appear in court on Friday afternoon for an initial appearance.
