A man accused of killing a 50-year-old Oskaloosa farmer faces a competency hearing.

Adam Hooper, 36, was back in a Jefferson County courtroom Tuesday, where a judge delayed a preliminary hearing in the case.

Instead, Hooper will have a hearing to determine whether he is competent to stand trial for the murder of Dale Kingsbury, 50.

Hooper was arrested Aug. 9, after authorities found Kingsbury’s body in a cistern on his farm where he and his wife had lived for 15 years.

Hooper had been living on the property working as a farmhand.

The judge set the competency hearing for Aug. 26.
