A new judge, Circuit Court Judge Kevin Walden, was assigned to the case after Monday’s hearing.
Nelson’s previous attorney had sought a new judge and a change of venue for the trial. It was not clear Wednesday if the change of venue was granted.
The brothers’ father reported them missing July 21 after they didn’t return from a visit to Nelson’s northwest Missouri home, where they had gone to collect a $250,000 debt, according to court records.
According to a probable cause statement, Nelson shot the brothers, put their bodies in 55-gallon barrels and allegedly burned the bodies. Nelson told investigators he dumped the remains on a manure pile and hid the barrels on his property, about 70 miles (110 kilometers) northeast of Kansas City, Missouri.
The remains were eventually found in Missouri and Nebraska.
