MARINETTE COUNTY (WBAY) -- Investigators are issuing a renewed plea to the public for clues into a double murder in Wisconsin 42 years ago.

In 1976, David Schuldes and his fiancee Ellen Matheys were killed at McClintock County Park in the town of Silver Cliff in Marinette County. Their killer has never been found.

With advancements in DNA technology, investigators used DNA from the crime scene and came up with a new composite sketch of the suspect. In releasing the new picture on Monday, Marinette County Sheriff Jerry Sauve commended investigators on their work in the 1970s.

"They had means then, working on blood types," Sauve said. "That was established through evidence like that, so they did good work back then allowing us to be where we're at with it today."

Investigators used a procedure known as phenotyping -- using the DNA to recreate a person's face, hair color, eye color and other features.

Anyone with information on the Schuldes/Matheys murders or who may recognize the suspect in the photos should contact the Marinette County Sheriff's Office at 715-732-7310 or Crime Stoppers at 1-800-427-5857.
