Narrative:

Descending out of 13000 ft, aircraft yawed to the right. Felt the aircraft shudder and heard a bang. It was my first officer's leg so I took controls. Power about 1900 pounds, propeller at 1450. Right oil pressure annunciator came on, looked at right itt and oil pressure zero on both. Shut down and feathered the right engine. No fire indication in cockpit. Passenger came up and informed of fire, so I discharged fire bottle just in case. Declared emergency and diverted to pbi. When on ground, fire marshal surveyed the right engine, no fire indication, so taxied to the gate. Fire marshal said no fire residue or indication. Passenger probably saw oil leaving exhaust. Callback conversation with reporter revealed the following information: reporter states the aircraft was a beechcraft 1900 pwred with a P&west PT6A-65B. The maintenance department preliminary check advised the reporter the high pressure turbine failed. He stated this was not the final analysis as the engine was shipped to P&west for repair.
