Nicole VanderHeyden went out with her boyfriend, Douglass Detrie, on May 20, 2016. They became separated and argued over calls and texts. Detrie went home. The following day Nicole was found dead near a field in Brown County, Wisconsin. Investigators found some of her clothing near a freeway entrance and blood and hair outside a neighbor’s home. Each discovery gave them another place to account for. [1]

Twelve steps
Detectives looked first at Detrie. His Fitbit logged twelve steps in the hours they were trying to account for. That small number gave them a reason to reconsider a theory that would have required him to be active during that stretch. The reading depended on whether he was wearing the device. The trial judge later let jurors hear the step counts and excluded the device’s sleep data. [1]
In June, Green Bay police interviewed George Burch in a separate vehicle investigation. Burch said he had been at a bar and had sent texts that would support his account. An officer asked about those messages, and Burch signed a consent form. The examiner made a full copy of the phone’s data. Police retained the copy after returning the phone. [1]

The sock and the stored file
In August, DNA from Nicole’s sock matched Burch. Brown County homicide detectives looked for prior police contact and found the Green Bay file. They reviewed the download, identified a Google account and saw that the phone had repeatedly accessed coverage of Nicole’s death. They obtained a warrant for Google’s records. The location data placed the phone near several places detectives already knew about, including the field and the freeway entrance. [1]
Burch testified that he met Nicole at a bar and that they left together. He denied killing her and told jurors that Detrie forced him to move her body. The prosecution disputed that account. The jury had both the phone’s movements and Burch’s explanation of how he came to make them. It convicted him of first-degree intentional homicide in 2018. He was sentenced to life without eligibility for release. [1] [2]

What jurors were allowed to hear
In 2021 Wisconsin’s Supreme Court upheld the judgment. The majority concluded that even assuming a constitutional violation, the officers’ conduct in this case did not call for excluding the phone evidence. The judges also upheld admission of the step records. Separate opinions disagreed about whether the phone search was lawful and whether the evidence should have been suppressed. The U.S. Supreme Court declined to review Burch’s case in January 2022. [1] [3] [4]
