Me thinks Timmy must have been trying to make it back home before his wife woke up. Which means he spent the night somewhere else. Occum’s razor for the data we know for sure. Why the hell would you drive 17 miles (34 roundtrip) for a cup of coffee and newspaper?
Does the black box data include GPS coordinates? If so, one could verify Timmy’s version of events. But I bet that data will never be released to the public.
