It appeared that the blocking stone for the entrance had been removedThis seems to be describing the state of the tomb before it was discovered by construction workers (though this point should be confirmed). Consistent with this, the report also notes that:
Two ossuary lids, found on the floor of the central room, under the fill of soil, indicate an ancient disturbance.Presumably these two points complicate an argument that the remains (including DNA material) in each box must correspond to the names on the lid. And they raise other questions. Do we know to which ossuaries the two lids belonged? Can we know when the grave was disturbed? And for how long it stood open? Tabor promises to add his own comments that may address some of these points.
