No, I don't think we do. I will say that if I had a loved one on that boat and there was only one person still missing, I would be apoplectic that it was my loved one who was not found. It is hard enough to know your loved one is deceased but to not have their body and think of them stuck in the deep would be excruciating. I hope all are found.
Hopefully, he or she will be found soon :*(
