In which case, the hole wasn't "pummelled" through the capstone, thus leading to the tomb's partial collapse.
For that to happen the stone would have to have been lying at the angle it is now either in the ground or above it and have a water 'trapping' area above it (which it hasn't) because the hole is perpendicular to the slope.
