A wealthy Utah mother charged with murdering her husband after admitting to an affair then having whiskey-fueled sex with him inadvertently led investigators to his body, police believe.
Jennifer Gledhill, 43, is accused of the September 21, 2024, shooting of Matthew Johnson, 51, as he slept at their $1 million home in Cottonwood Heights, near Salt Lake City.
She is said to have killed Johnson, who is the father of her three children, after he accused her of an affair during an argument that culminated in a night of whiskey-fueled sex and his death.
However, his remains have yet to be found, and Gledhill has pleaded not guilty to the charges.
A search warrant unsealed earlier this month shows that police believe Gledhill was wearing an Oura Ring when she allegedly committed the crime, ABC4 reported.
Court records show the warrant, which was filed in February by the Salt Lake County District Attorney's Office, sought records and data from Oura Ring accounts linked to both Gledhill and Johnson from September 20, 2024, to October 1, 2024.
'If Jennifer was wearing the Oura Ring during the time the [that] Matthew's body was disposed of, that ring will contain location information that the geolocations didn't, because she had turned off that device,' the warrant stated.
Oura Rings track activity, heart rate, body temperature and they can record GPS locations with time and date stamps.

Photos from earlier in the day of the alleged murder show Gledhill was wearing her fitness ring, and the Utah National Guard Unit Johnson was assigned to confirmed he also had a ring, according to the local news station.
Investigators previously used GPS data from Gledhill's car to show that she had visited remote sites in northern Utah before and after Johnson's death, according to prosecutors.
Gledhill was arrested after she allegedly confessed to the killing to her unnamed lover, who then told the police, according to the Salt Lake County District Attorney's office.
Her parents Thomas and Rosalie Gledhill have also been arrested for allegedly helping their daughter cover up the murder by deep-cleaning her home afterwards.
Despite alleged efforts to remove any signs of the bloody murder from the scene of the crime, gruesome evidence was unearthed in court.
Prosecutors showed images they say prove that Gledhill brutally killed Johnson as he slept, before dragging his lifeless body and the blood-soaked evidence out of their home.
The court saw images of blood stains on a carpet that was underneath the bed in the couple's bedroom, where detectives believe Johnson was killed. DNA analysis confirmed it was Johnson's blood, per prosecutors.
Prosecutors also exhibited a GPS tracking map showing that Gledhill traveled north the day after the alleged murder to a location where Johnson's red truck was found.

At the same location, police say they found a vehicle storage container floating in a creek. Investigators say the inside of the container tested positive for Johnson's blood, as reported by Fox 13.
An eerie snap of the couple's bedroom where the whiskey-fueled sex and subsequent murder took place was also shown in court.
GPS data also revealed that Gledhill traveled to another location in the same county where police found the couple's mattress and pillows wrapped up in a rug from their home.
Prosecutors also showed the court a 2023 image they say shows Johnson by the same rug Gledhill dumped alongside the mattress.
Gledhill was allegedly having an affair with a man who told police she confessed to shooting Johnson.
She allegedly said she put his body in a storage container and then loaded it into her minivan.
Gledhill is expected back in court for a preliminary hearing, and her trial is scheduled to start in December.
