The most shocking piece of information that has come out thus far is reported on this Wiki. Apparently, WRGB reported on October 20 that the glass windows on the boat had acted like a box. This trapped the passengers inside of the boat and the only way out was smashing through the windows. It had also been confirmed that the 20 people that died had drowned due to the glass windows trapping them inside.
There is very little other information coming out from news agencies these last two weeks, as we all wait for the NTSB report.
