26-year-old Brittany Green is charged with tampering with evidence...
Her bond had been set at 150- thousand dollars ... but it was reduced to 100- thousand.
Her mother, 49-year-old Terri Green, faces the same charge.
She was being held on a 250- thousand dollar bond ... but that was reduced to 100- thousand.
30-year-old Justin Wayne Green -- Who is Terri's son and Brittany's brother -- remains jailed, on a one million dollar bond.
Stephanie Heaston Corral, described in affidavits as a friend of Brittany, is also charged in the coverup of the crime, and had previously bonded out of jail.
Clay County authorities believe Justin Green shot and killed Jose Ramirez of California about five years ago ... and then buried the body in a shallow grave near a trash pit outside Petrolia.
A tip led authorities to the crime scene.
