The parents of a Utah woman accused of murdering her husband after he confronted her about an affair have been arrested for allegedly helping her clean up the crime scene.

Thomas Ray Gledhill, 71, and Rosalie Christianson Gledhill, 67, were arrested Thursday on four felony counts of first-degree obstruction of justice, ABC4 reported.

The couple allegedly helped their daughter, Jennifer Gledhill, to clean her home after she supposedly fatally shot her husband, Matthew Johnson, on Sept. 21, the outlet said.

Witnesses placed the elder Gledhills at their daughter’s home over a five-hour period around the time of the killing, police said.

Jennifer Gledhill reported Johnson missing on Sept. 28 — but a man subsequently came forward and told police he had an “extramarital affair” with her and that she confessed to killing her husband, according to prosecutors.

The man — who has not been identified publicly — claimed Gledhill told him that her husband “yelled at her” about the affair on Sept. 20.

“The defendant told the informant that she shot Mr. Johnson [the next day] as he slept in their bed,” Salt Lake County District Attorney Sim Gill said.

“She told the informant that she put Mr. Johnson’s body into a rooftop storage container, slid him down the stairs of their home, and loaded his body into the back of their minivan.”

Gledhill “then took her husband’s body north, dug a hole, and buried him in a shallow grave,” the DA added.

She also allegedly destroyed Johnson’s phone, ditched his truck in a different part of the neighborhood and brought her own car to a car wash, where surveillance cameras caught her “thoroughly” cleaning it out.

Police tracked Gledhill’s phone’s GPS data to the exact spot where the truck was later found, but they still haven’t found Johnson’s body.

The mom of three was arrested last week and charged with nine felonies, including first-degree murder.

Her parents were interviewed by police earlier this month, ABC4 said.

The couple denied helping their daughter clean her home. When their cellphones were seized, police found that the devices had been reset and that any information from before Gledhill’s arrest had been lost.
