I'm a little confused by the report. The S/V Liberty was rescued a month ago by the Canadian Coast Guard or there was never a mission involving a S/V Liberty?
They know the owner's name is Bunn or they don't know where the sailboat came from?
They saw an unidentified guy and his dog backpacking? No one knows if he's heading to the Caribbean or back to Wisconsin?
I believe there has been a fundamental mistake by the good people of Canada. That boat is clearly owned by Atticus, the dog who also is featured in the story, 'To Kill a Mockingbird'. Just look at the collection of chew toys aboard and that is clear.
I feel bad that the owner suffered such a sad disaster, but looking at the contents and condition of that boat when docked after the first rescue, and the idea that the owner simply abandoned a shipwreck like that, there may be some mental issues at play here.
Or
The backpacker is a red herring and the unlucky sailor has been lost at sea. Either way, that is a good looking dog. I hope Atticus and his human are all right.
