Murder With My Husband – Episode 317: The Fitbit That Solved a Murder – Nicole VanderHeyden

Release Date: April 20, 2026
Hosts: Peyton Moreland & Garrett Moreland

Overview of the Episode

This episode focuses on the 2016 murder of Nicole VanderHeyden (Nikki), a mother of three from Green Bay, Wisconsin, and the critical role that modern technology—most notably, a Fitbit—played in both identifying her killer and protecting an innocent man from a wrongful conviction. Peyton sets out to highlight not just how tech helps solve crimes, but how it can also prevent miscarriages of justice in the face of misleading circumstantial evidence.

Key Discussion Points & Insights

1. Technology in Crime & Justice

• Opening Commentary on Modern Crime-Solving:
  Peyton reflects on how technology (geofencing, digital forensics, genetic genealogy, etc.) is shaping modern investigations:

  "Googling one damning search phrase can literally lead to an arrest." (05:16)
  She emphasizes that new tech doesn't just catch criminals, but also prevents wrongful convictions.

2. The Life of Nicole VanderHeyden

• Background:
  Nicole, known as "Nikki," was a beloved mother and teacher who prioritized others and found solace in nature. After divorcing her first husband, she met Doug Dietree and had a child with him.
• Context for the Night:
  Nikki and Doug, exhausted parents, sought a rare night out at a Steel Panther concert with friends (08:53).

3. The Night of Nikki's Disappearance (May 20–21, 2016)

• Sequence of Events:
  • Nikki and Doug go out but split up during the night after a minor argument about Doug socializing with old friends.
  • Nikki leaves upset, seen on surveillance dancing and socializing at the "Sardine Can" bar until 11:30pm.
  • After heated texts and calls, Nikki storms out, refusing a ride from friends and is last seen by them (13:40–15:00).
  • Doug and his friend Greg claim to search for Nikki, eventually returning home without her at 2:40am.

4. The Investigation Begins

• Discovery of Nikki's Body (01:30pm, May 21):
  A farmer finds a naked woman's body, later identified as Nikki, three miles from her home. She'd been strangled, beaten, and fought for her life (22:00-23:37).
• Doug as the Initial Suspect:
  Circumstantial evidence and their rocky relationship put Doug in the crosshairs:
  • He was the last known person to see her.
  • Blood, a matching shoe imprint, and a cord were found near his home (39:25–41:45).
  • Peyton: "While searching their garage, detectives spotted blood on the floor... Air Jordans... some bloody smudges on the bottom." (40:41)

5. The Turning Point: Exonerating Doug with Technology

• Technology Provides an Alibi:
  • Doug’s car never left the bar parking lot; Nikki’s car didn’t move (44:25).
  • Fitbit data proved Doug only took 12 steps during the critical time window (46:20):

    Peyton: "A Fitbit tracks your movements entirely...which means there's no way he could have killed his girlfriend and moved her body in 12 steps." (46:21)

  • Blood in the garage was from a turkey; blood in the car from a child; shoeprint didn’t match (47:19–47:56).
  • Doug is freed; police realize they're back to square one.

6. The True Killer: George Burch & Digital Forensics

• Breakthrough via DNA:
  DNA on Nikki’s sock matches George Burch, a recent Virginia transplant with a violent past (49:24).
• Digital Trail:
  Police had previously cloned Burch’s phone during an unrelated investigation, revealing:
  • GPS + WiFi logs place him at Nikki's house at her time of death
  • His phone moves from Nikki's house to the dump site, then to where her belongings are found (52:01–52:41).
• George Burch’s Ridiculous Defense:
  On trial, Burch tries to claim Doug committed the murder (55:14), but Fitbit and data prove otherwise.

Notable Quotes & Memorable Moments

• On Wrongful Convictions & Technology:

  "This is definitely something about technology that we don't often go over in true crime... advances have made it easier to not put the wrong person in prison." (06:40) — Peyton

• Surprising Doug’s Innocence:

  Peyton: "Little details start pointing away from Doug… For example, Doug left his car overnight at the watering hole. He had to go get it the next day." (44:25)

• Garrett’s Reaction to Doug’s Ordeal:

  "Shoot. It's not Doug. Yeah, I just ripped Doug a new one and it's not Doug. Why would you let me do that?" (43:12)
  "Doug just got drugged through the wringer." (54:15)

• On the Power and Privacy of Technology:

  "Most of my devices, if I'm not doing anything wrong, should have my back... They offer indiscriminate proof should I ever find myself in an unthinkable situation. Doug had his Fitbit." (57:55) — Peyton

• The Tragedy of Random Violence:
  Nikki’s story is a chilling reminder that the most tragic crimes can sometimes result from simply crossing paths with the wrong person.
