Four women have appeared in court charged with not allowing a body to be given a proper burial.
The last confirmed sighting of Geoffrey Howard Sturdey, from Tregaron, Ceredigion, was in October 2008.
He was aged 60 at the time.
The investigation follows the discovery of the remains of a man, thought to be Mr Sturdey, on a remote smallholding near Tregaron.
Today's hearing took place before magistrates in Haverfordwest.
Rebekah Sturdey aged 56, and Boque Ore Adie, aged 43, have been remanded in custody accused of benefit fraud of more than £60,000.
Hazel Adie, aged 20 and Karmel Adie, aged 25, were released on bail.
All four are due before Swansea Crown Court on July 5.
