This new Maui News article on the Hana sighting is a must read. The sheer serendipity of this sighting is incredible. Maui News App put it up right away today, no paywall on the app.
The reasons she had for truly noting Steven as he went by are extremely believable. The thing is (if you have not read it yet), he DID NOT SEE her or know he was seen. This could not have influenced his decision to put himself with Charli for the police; but we still have other reasons.
He now has time to drop Nala in Nahiku if he had a reason to go to Hana, but why was he in Hana? How long a drive from Paraquat's to Hana at night, and how long back? The time frame for sighting is 9:30--11:30, but
Earliest he leaves Haiku is 8:30
the phone pinged Honomanu at 11:00 (I'm rounding off the 4 min).
The fire started at Jaws 12:30.
Can someone make this work out where he's not driving most of the time?
