Summary
Written by a model from the transcript; not yet reviewed.
In the summer of 1976, engaged couple David Shuldees and Ellen Mathies were shot and killed at a remote campground in McClintock Park, Wisconsin. The vicious double homicide baffled investigators for decades, cycling through false leads, flawed blood-typing evidence, and even an erroneous evidence destruction order in 1980 that compromised key lab materials. The case finally broke in 2018 when genetic genealogy and DNA phenotyping led authorities to Raymond Van Evenhoven. Investigators matched his DNA to evidence from the crime scene, culminating in his 2019 arrest, 2021 conviction, and subsequent life sentence at age 85.
The podcast details the meticulous investigative steps that spanned over forty years, contrasting the typewriter-era police reports of the 1970s with modern familial DNA databases. Host Delia D'Ambra examines witness accounts, a suspect composite sketch, and Van Evenhoven's prior criminal history, raising chilling questions about whether other unsolved crimes in the region might be tied to him.
- Investigators used familial DNA matching through public databases to identify a suspect decades after the crime occurred. 28:20
- Flawed forensic conclusions early in an investigation can derail progress for years by sending detectives down the wrong path. 22:16
- Preserving physical evidence is crucial, as advancements in DNA technology can generate profiles from decades-old samples. 24:04

About this episode
In July 1976, a young couple camping in a Wisconsin state park were both shot dead. For forty years, investigators had a sketch, a plate number, a blood type — and not enough DNA to test. The investigation would span decades until the truth eventually surfaced. View source material and photos for this episode at: parkpredators.com/the-decades
