David Lackey is scheduled to go to trial September 29. Jade Stigall is scheduled to go to trial October 13.
The two are charged with murder and conspiracy to commit murder in connection with the death of Joe Nelson.
Nelson's body was found in February on a conveyor belt near the Alcoa Power Plant. An autopsy showed he had been shot in the head.
The case against several other defendants in the case is still pending.
