The obvious assumption, I would think, was that the doctor caught a ride over, whether by air or sea, with someone already going to Molokai. Since the accident had just happened on the 11th, and the autopsy was performed on the morning of the 13th, there were probably police officers going to Molokai. Since this is all Maui County, I imagine the police have their own means of transportation to access all areas of the county. So why would Dr. Harle bill back the government when she was riding in their boat, plane, or helicopter?
Oh - and if she caught a ride with an MCPD flight that just happened to be going to Molokai that morning (Molokai has its own station so inter-island travel is not usual), there still would have been some record of it.
And at the very least there is supposed to be a recording of the autopsy being done - which would make the travel issue moot. There is no recording.
Also, there would not be police officers going to Molokai from Maui on Dec 13th because the MCPD had already decided on the evening of the 11th (after first saying it WAS a normal case and then changing their mind at a very peculiar time...) that the investigation following the plane landing was an “outside assistance” case - that is, that HRS 841-3 was not in effect and the only reason even the folks on Molokai were involved was to assist some other agency. If the Molokai branch of the MCPD didn’t even have jurisdiction and was simply helping somebody else out, then FOR SURE the Maui branch had no reason to be involved, and especially not to go there to Molokai.
