Investigators are leveraging data from Oura smart rings to locate the burial site of a Utah National Guardsman allegedly murdered by his wife. The wearable technology, worn by both the victim, Matthew Johnson, and the suspect, Jennifer Gledhill, tracks time- and date-stamped GPS data that police hope will pinpoint the location where Johnson's body was concealed.
Search warrants unsealed by the Salt Lake County District Attorney’s Office show investigators targeted Oura ring data for both Gledhill and Johnson between September 20 and October 1, 2024, the period during which the suspected murder occurred. Authorities believe Gledhill, 42, killed her husband in his sleep after a night of drunken intimacy during which she admitted to having an affair.
Gledhill has pleaded not guilty to murder and waived her right to a preliminary hearing. She was arrested on suspicion of murder after allegedly confessing to an alleged lover, though she did not disclose the burial location to him.
According to investigators, Gledhill’s alleged lover stated that Johnson had confronted his wife on September 20 after learning of her infidelity. The following day, Gledhill allegedly shot Johnson as he slept. Investigators’ reports state that Gledhill then placed her husband's body in a rooftop storage container, moved it down the stairs, and loaded it into the back of their minivan.
Following Johnson's death, Gledhill reportedly reported him missing on September 28, eight days after detectives believe he was killed. Surveillance footage reportedly shows Gledhill cleaning out the minivan after the alleged killing. Police allege Gledhill turned off her phone and other electronic devices before driving the minivan to bury her husband in a shallow grave.
Gledhill’s parents, Thomas and Rosalie Gledhill, have also been arrested and charged, with investigators believing they assisted their daughter in concealing the crime. The Utah National Guard unit Johnson belonged to confirmed he owned an Oura ring.
