I'd postulate that to the external "spectator" an object would never reach the singularity due to time dilation beyond the event horizon. The matter would simply be stretched out over the course of eternity "towards" the singularity in whatever spiral if any spin is present inside.

In fact the density of any materia inside the event horizon might be so high that matter wouldn't be able to transit the event horizon itself until it itself was compacted down to the density of the matter beyond, due to buoyancy, and the density at the event horizon just happens to be roughly where light can be "pushed" away due to buoyancy and lensing.

Just late night bed thoughts. Probably worth nothing as a nonphysicist.
