Parents of a Utah mother accused of killing her husband in his sleep are now facing charges

The parents of Jennifer Gledhill, a Utah mother accused of fatally shooting her husband in his sleep after he learned of their extramarital affair, have been arrested after authorities allege they helped Gledhill commit the murder cover up.

Thomas Gledhill, 70, and Rosalie Gledhill, 67, were arrested during traffic stops in Salt Lake County on Thursday, October 24, Cottonwood Heights police said in a news release shared with PEOPLE. According to police, both were jailed on multiple felony counts of obstruction of justice in connection with the death of Matthew Johnson in September.

It is unclear whether they have filed pleas or retained attorneys to speak on their behalf.

The parents are accused of helping Jennifer clean up the house where authorities believe she shot Johnson on Sept. 21 and getting rid of evidence related to the murder. Their arrests come just over a week after the Salt Lake County District Attorney's Office announced that Jennifer had been charged with first-degree murder and other crimes in connection with her husband's killing.

Johnson, a member of the Utah National Guard, was reported missing by Jennifer on Sept. 28, prosecutors previously said in a statement. Jennifer was arrested in early October after an informant who claimed he was having an affair with her told police that she allegedly confessed to fatally shooting Johnson in his sleep after learning about the affair, prosecutors said.

Jennifer also allegedly told the informant that she placed her husband's body in a storage container and placed it in her minivan before burying the body in a shallow grave, according to prosecutors. When the informant asked her about the bruises on her body, Jennifer allegedly said she caused them by cleaning the crime scene and transporting the body.

According to two probable cause affidavits, one for each parent, witnesses told police that Thomas and Rosalie were seen cleaning their daughter's house over a five-hour period on September 24, although Rosalie claimed to authorities that they were there for about an hour. According to the affidavits, both parents refused to have the house cleaned.

Thomas reportedly told investigators during questioning that he didn't remember much of that day, prosecutors previously said. The affidavit also states that cell phone records show that Thomas was the only person who called Jennifer on the day she was believed to have buried Johnson's body.

After authorities searched Jennifer's apartment, they allegedly found a bloodstained stain on the carpet under the bed in the master bedroom and discovered that the wall behind the bed was covered in bleach and that the mattress in the room was new, the release said . Prosecutors said Gledhill's mother allegedly told investigators that she purchased the mattress for Gledhill after she asked her to do so, the release said.

According to the affidavits against the parents, prosecutors believe Johnson was killed on a discarded mattress and remains missing along with the victim's body.

Tests revealed that the blood stain on the carpet came from “a single male source,” the release said. However, prosecutors said further testing was ongoing to confirm whether it matched Johnson's DNA.

Authorities also executed a search warrant at Gledhill's parents' home in early October and claimed they found a plastic bag containing a loaded gun similar to the one she allegedly showed the informant on Sept. 19, the release said.

Authorities claimed in the affidavits that both parents did not cooperate with the investigation or provide any information leading to the location of Johnson's body.

“We urge the public not to draw conclusions as the investigation and prosecution are ongoing,” Cottonwood Heights police said in the news release.

According to ABC 4 and KUTV, a judge has ordered Jennifer to have no contact with her three children. It is unclear whether she has entered a plea, and PEOPLE was unable to identify an attorney who could speak on her behalf.
