Bruce Anthony Coss, 48, is charged with killing Darren Royce Willis after a night out at the Imperial Hotel in Bingara on December 10, 2010.

Robert James Stonestreet is charged with concealing a serious indictable offence, namely the alleged murder of Mr Willis.

The pair's charges were listed in Moree Local Court on Monday for charge certification, where the Crown would confirm the charges and case against them.

But the case was adjourned again. Magistrate Roger Prowse ordered the parties to reappear in court again in mid-August where the case is listed for charge certification again.

Neither Coss or Stonestreet made any application for bail and it was formally refused by Mr Prowse.

The pair will remain in custody and will front court again via video link on the next date.

Both have not been required to enter pleas to the charges.

Detectives allege Coss struck Mr Willis near his Bingara home, and killed him. He's then alleged to have dumped Mr Willis' body at an unknown location. His remains still have not been found.

New England detectives allege Stonestreet has key details on the general location of Mr Willis' remains.

Police allege he was present when the murder occurred and did not come forward with information during the investigation.

The pair have been in custody since their arrest in Bingara in October last year by officers from Strike Force Barca - the police operation that has been investigating Mr Willis' murder.
