The Murders of the Carman Family - Thoughts?! I'm torn!

I'm so torn. I watched it last night, just piqued my interest because I live on Long Island and have been out on Block Island which is kinda where some of it takes place. To possibly jog some people's memory, it was a murder case where a mother and her son go out on their boat (Linda and Nathan Carman), and as per the son's testimony, the boat sank and Nathan was in an emergency blow up cube-like thing and found after being on the open ocean for 8 days, and his mother and the boat were never found.

Usually when I watch a doc, I feel one way or another, almost never ambiguous. But this one has me torn, for both the mother/daughter Linda, as well as the father/grandfather John Chakalos.

I know that this is "just another 90 minute true crime documentary" that Netflix churns out, so I wouldn't be surprised if no one's seen it or heard of it, but I still wanted to cast a line out and see if anyone has! And if so, what are your thoughts on both of the deaths of Linda Carman and John Chakalos?! Do you think that >! Nathan is responsible for either, or both of the deaths of his mother and grandfather? Do you think Nathan is responsible for his mother but not his grandfather? !< I'd love to hear any input! What are your thoughts about the Chakalos family as a whole? Do you think any other people (they mentioned the possibility of it being a "hit" due to mob relations), or family members could've been responsible for the murder of John Chakalos? Thoughts on motives as well as the financial aspect?

I'm up to chat about any of it!
