Bingara murder: Bruce Anthony Coss and Robert James Stonestreet to stay in custody until May, charged in connection to Darren Willis' murder

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.

Both had their cases listed for mention in Moree Local Court on Monday, but during the proceedings, both matters were adjourned for four months.

Magistrate Lisa Stapleton ordered the brief of evidence for Stonestreet be served on his defence before the case returns to court in early-May.

Neither Coss or Stonestreet made any application for bail and it was formally refused by Ms Stapleton. She ordered the pair remain in custody until May.

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.

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

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