Chad Daybell, the stepfather of two children who were found dead in his backyard in Idaho, has entered a plea of not guilty to two felony counts of concealment or destruction of evidence.

East Idaho News reports that Daybell’s attorney John Prior entered a not guilty plea on his client’s behalf and requested a jury trial.

On Tuesday, investigators executed a search warrant of Daybell’s property in Salem and found the remains of 7-year-old JJ Vallow and 17-year-old Tylee Ryan after a brief search of the yard that appeared to be targeted. Daybell is married to the children’s mother Lori Vallow, who is in jail in Madison County awaiting trial on felony charges of child desertion.

Authorities have not revealed what led them to believe the children would be found at Daybell’s home. The East Idaho News report notes that a probable cause affidavit was sealed by the court, reportedly because it “is necessary to prevent harm to any person or persons.”

According to the report, Daybell’s attorney has also submitted a request for discovery documents and asked the prosecuting attorney for any pertinent statements made by Daybell and a potential co-defendant, who is not named.
