Narrative:

After a smooth touchdown (landing) no abnormal conditions were experienced. Then when exiting the active runway, aligning the aircraft with the taxiway centerline, the aircraft began to pull to the r-hand. Left rudder and brake input were applied to counteract the right pulling. Suddenly the nose of the airplane dropped. The propeller hit the ground and kept spinning. ATC was contacted for assistance. The engine was shut down manually. The front end of the aircraft was resting on the nose strut and the nosewheel was 3 ft behind the nose strut. The main bolt was missing along with 1 end cap for the nosewheel.
