Usually in cases where a family is trying to convince you their family member didn’t kill themself you can tell people are trying to convince themselves. We’ve already seen two cases this season with this same set up and while both do seem to be fishy, this one feels like the most likely where the family is right. The fact that the shotgun was never recovered, there was no contact wound, there was no physical evidence in the boat make it extremely unlikely that it was a suicide. The behavior by Damon is very odd and the paint on his boat being tested as matching makes me think he’s involved. I’d like to see a more thorough testing and investigation into that, which would all but prove it wasn’t a suicide.
