The case sped up after McNeill decided not to take the stand in his own defense.
The defense had requested to see the state's audio-visual display, but that request was denied Monday.
A charges conference was held though. It is a session between the two sides about the ins and outs of the charges and what to expect for closing arguments.
The state plans to take all Tuesday morning for closing arguments, and will wrap by lunch.
The defense, which did not present a case, only plans to take an hour. So closing arguments will end Tuesday.
During closing arguments, the state will be allowed to say that "circumstantial evidence" shows McNeill knew where the body was because his attorneys told investigators.
The jury will begin deliberating on Wednesday. The judge predicts it will take several hours, if not days, for the jury to reach a verdict.
The final stages of the trail begin at 9:30 a.m. Tuesday.
