Startling revelations have surfaced in the case involving a Utah woman, a wife, and a mother of three, who allegedly murdered her husband, a National Guardsman, following his allegations of her infidelity.

At 42, Jennifer Gledhill faces nine serious charges, including first-degree murder, five second-degree counts of obstructing justice, one second-degree charge of possessing drugs with the intent to distribute, one third-degree charge of body desecration, and one third-degree count of witness tampering, as stated by the Salt Lake County District Attorney’s Office.

The accused killer was arrested in early October 2024.

Initially, the prosecution’s case relied on her admission recorded by a man initially identified as a confidential informant. It soon emerged that this man was her lover, casting light on the love triangle believed to have led to the death of 51-year-old Matthew Johnson in late September 2024.

Now, law enforcement has released what, exactly, Gledhill allegedly told the man she was sleeping with about the crime.

According to prosecutors, Johnson arrived home on September 20, 2024, and confronted his wife about the affair. Then, after the clock struck midnight on September 21, 2024, Gledhill allegedly shot Johnson with a 9 mm pistol as he slept in their bed.

On the night of Sept. 22, 2024, Gledhill went to her paramour’s home and told him what she had done, in detail, prosecutors alleged.

Prosecutors described in a press release that Gledhill confessed to the informant, claiming she placed Johnson’s body into a rooftop storage container, maneuvered it down their home’s stairs, and then transported his body using their minivan.

Gledhill then allegedly “smashed” Johnson’s phone and ditched his truck in a nearby neighborhood. Next, she drove his body “north” and buried him in a shallow grave, according to prosecutors. The other man is said to have noticed bruises on Gledhill’s body during this initial conversation; she allegedly told him she got the bruises while burying her husband’s body and cleaning the house to rid it of evidence.

That first confession scared the other man, according to law enforcement. So, during a future discussion, he was prepared, prosecutors said, according to a recent report by People Magazine.

In a follow-up phone call, which he recorded, the lover said he was afraid of her. This expressed fear prompted a chilling response from Gledhill, law enforcement alleged.

“Wow, if you think I could even hurt a fly,” she allegedly said. “Like he just, he is, he’s not a person. He wasn’t a person anymore. He wasn’t Matt.”

On Sept. 28, 2024, Gledhill reported Johnson missing.

Meanwhile, the lover had been collecting a trove of evidence – screenshots and the audio of the phone call – to supply to authorities.

On Oct. 2, 2024, Gledhill was arrested.

Days after that, the woman’s parents, Thomas Gledhill, 71, and Rosalie Gledhill, 68, were arrested and charged with obstruction of justice for allegedly assisting their daughter after the fact by cleaning the home and purchasing a new mattress to replace the one where the victim was killed.

The alleged removal of evidence did not inure to the defendants’ favor.

During a subsequent search of the residence in Cottonwood Heights – a small city and suburb of Salt Lake City – investigators allegedly discovered blood on three bed slats and a “large blood-stained spot in the master bedroom carpet underneath the bed,” according to a probable cause affidavit.

“Matthew Johnson is not missing,” Salt Lake County Deputy District Attorney Emily Paulos said during a Feb. 28, 2025, court hearing. “Matthew Johnson was murdered by the defendant.”
