Here is how investigators cracked the case.
## The Investigation Breakthroughs
For years, the investigation stalled because Dale claimed Dee had simply packed up and left their "toxic" marriage. Without a body, proving murder was incredibly difficult. The prosecution ultimately broke through his defense using three key pillars:
* **Digital Surveillance & Inconsistencies:** Investigators discovered Dale had been extensively stalking Dee, utilizing tracking apps and hidden cameras to monitor her movements. When police scrutinized his timeline on the night of April 24, 2021, his statements were riddled with inconsistencies, and Dee’s own digital footprint (phone activity, bank accounts, social media) completely ceased early that morning.
* **The Circumstantial "No-Body" Arrest:** In a rare move, Michigan State Police arrested Dale in November 2023 before finding Dee's remains. They built a circumstantial case proving she hadn't run away by highlighting that she left behind her purse, passport, and shoes, and demonstrating that she had not accessed any hidden financial accounts (despite Dale's claims that she stole money to live abroad).
* **The Fertilizer Tank Discovery:** The ultimate physical breakthrough happened in August 2024. Operating on theories developed from Dale's access to welding equipment, investigators executed a search warrant on his Paragon Road agricultural property. They found Dee's body hidden inside a dormant, resealed anhydrous ammonia tank. She was wrapped in a blue tarp and duct tape.
