From my experience yes, this is what might likely happen. IF the closing statements get done early enough, like 5 or so, then dinner will be ordered in to the deliberation room.
And they will have a very short night doing what is often done to start with.
They will discuss who the foreman will be and vote on it and agree on someone. And then they will probably take a quick anonymous vote, asking who votes guilty, or not and if so, what charge they would vote for now. It is the way to get an idea how things are looking to start with.
Then on Monday morning they will begin going through the evidence and discussing it bit by bit. HOPEFULLY everyone is on close to the same page. Sweet Dreams.
