MARINETTE COUNTY, Wis. (WBAY) - It's been 42 years since a Green Bay couple was murdered during a camping trip in Marinette County, and investigators hope new composite photos of the suspect will help them catch the killer.
On July 9, 1976, David Schuldes and Ellen Matheys were killed as they walked in McClintock Park in the Town of Silver Cliff.
Schuldes, 25, was found shot to death in the park. Matheys, 24, was sexually assaulted and shot to death. Her body was found in a wooded area outside the park.
The case went cold. The Sheriff's Office on Monday released a new composite photo of the suspect that was created using DNA technology.
"For closure for us, for the victim's family, we certainly would take it to the tomb stone and see about making the match that way," said Sheriff Jerry Sauve, Marinette County Sheriff's Office.
A Snapshot Phenotype Report shows what the suspect would look like at age 25 and what the suspect would look like age progressed to age 65.
The DNA analysis found the suspect would have had fair-to-very fair skin color (93.4 percent confidence), blue/green eyes (92.6 percent confidence) and reddish brown/black hair (97.4 percent confidence).
Snapshot DNA Analysis is a self-proclaimed "cutting-edge forensic DNA analysis service."
DNA Phenotyping was used to create the composite photos of the Schuldes/Matheys suspect.
Here's how it works: Snapshot says phenotyping technology reads parts of the genome that show the "differences between people." It takes information from DNA and makes predictions on what the face looks like and skin color, eye color and hair color.
The technology has helped other investigators solve cases and develop leads.
