The fate of a man charged with murder could be in the hands of a jury Tuesday.
Mark Coleman is charged with killing his wife, Trina.
The defense wrapped up its case Tuesday morning.
Closing arguments were expected Tuesday afternoon.
Last week, Coleman's taped confession was played for jurors.
On the tape, Coleman tells police he thought his wife was cheating on him and that's what started the argument, but he says the gun fired by accident.
