One of the jurors becomes so sick that that juror cannot continue to discharge that juror's duty and there is no alternate juror;3. Any accident or other cause prevents keeping the jurors together for deliberation;4. Upon the expiration of such time as the court deems proper, it appears that there is no reasonable probability that the jurors can agree upon a verdict; or5. The court finally adjourns.
