What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

The appropriately rated and qualified PIC went through the check list to verify low oil pressure and shut down the engine and verified the oil pressure warning was real and not an indication. The emergency check list was completed then the PIC declared an emergency with spi approach control and elected to turn back to the spi airport. The flight made an uneventful landing, taxied to the terminal and deplaned all passengers and crew.
